SUBJECT: Islam — The World’s Second-Largest Religion and Fastest-Growing Faith

ADHERENTS (EST. 2025): ~1.9 billion — approximately 25% of global population. Majority religion in 49 countries. Fastest-growing religion by absolute numbers and proportion.

MAJOR BRANCHES: Sunni (~87–90%)  ·  Shia (~10–13%)  ·  Ibadi (Oman, <1%)  ·  Sufi orders (cross-denominational mystical tradition)  ·  Ahmadiyya (considered non-Muslim by most mainstream bodies)

CANONICAL TEXTS: The Holy Quran (believed to be the direct word of God as revealed to Muhammad). The Hadith collections (recorded sayings and actions of Muhammad). The Sira (prophetic biography). The Sunnah (the Prophet’s normative practice).

FOUNDING CONTEXT: 7th century CE, Arabian Peninsula. The Prophet Muhammad received, according to Islamic belief, the first revelation in 610 CE in a cave on Mount Hira near Mecca. Islam presents itself not as a new religion but as the final, corrective revelation of the same monotheistic tradition shared with Judaism and Christianity — restoring what those traditions had distorted.

DOSSIER SCOPE: This file is a complete archival record covering: the historical record, the core belief system, textual and transmission controversies, physical and archaeological evidence, the Sufi and esoteric layer, institutional and political controversies, and the contemporary global landscape.

DIRECTORATE POSITION: Strictly archival. This file documents what has been believed, what has been transmitted, what has been disputed, what has been suppressed, and what has been committed in the name of the subject. The same evidentiary standard applies to theological claims and to documented historical events. Nothing in this file constitutes a verdict on the truth of Islam.

Islam originated in the early 7th century CE on the Arabian Peninsula, in the region historically known as the Hejaz — the western coastal strip of what is now Saudi Arabia, containing the cities of Mecca and Medina. The Arabian Peninsula at this time was a tribal polytheistic society with Jewish and Christian communities scattered throughout, and Mecca was already an established religious and commercial centre, home to the Kaaba — a cube-shaped structure containing numerous idols that served as the focal point of inter-tribal religious practice.

The Historical Muhammad — What Secular History Confirms

Muhammad ibn Abdullah was born approximately 570 CE in Mecca, into the Quraysh tribe. His parents died in his childhood; he was raised by his grandfather and then uncle. He worked as a merchant, married the businesswoman Khadijah (his first and, during her lifetime, only wife), and by his own and followers’ accounts began receiving divine revelations in approximately 610 CE at age 40, while meditating in the Cave of Hira on Mount Jabal al-Nour. His existence as a historical figure is not seriously disputed by secular scholarship. The non-Muslim historical record is thinner than for Jesus — the earliest external references are from Byzantine and Syriac sources in the decades following his death — but the historical consensus accepts Muhammad as a real 7th-century figure whose movement transformed the Arabian Peninsula and subsequently most of the known world within a century of his death.

After the first revelation, Muhammad began preaching monotheism in Mecca — a message directly threatening to the city’s polytheistic economy and to the Quraysh tribe’s control of the lucrative pilgrimage trade. Facing persecution, he and his followers migrated to Medina in 622 CE — the Hijra, which marks year one of the Islamic calendar. In Medina, Muhammad consolidated political and religious authority, issued the Constitution of Medina (establishing a multi-religious proto-state), and conducted a series of military campaigns against Mecca and other tribes. By 630 CE, he had returned to Mecca in triumph, destroyed the idols in the Kaaba, and unified most of the Arabian Peninsula under Islamic rule. He died in 632 CE.

The Early Conquests — The First Century of Islam

Within one century of Muhammad’s death, Islamic armies had conquered the Persian Sassanid Empire in its entirety, seized the Byzantine Empire’s richest provinces (Egypt, Syria, the Levant), expanded across North Africa to the Atlantic coast, crossed into Iberian Spain (711 CE), and reached the gates of Constantinople. This military expansion was the most rapid in recorded history. It was driven by a combination of factors: religious motivation, the political unity provided by Islam to previously fractious tribal confederacies, the simultaneous exhaustion of the Byzantine and Persian empires from decades of mutual warfare, and — historians debate the relative weight of each — the genuine appeal of a monotheistic, egalitarian message to populations under heavy taxation by their existing rulers. The conquered territories were generally permitted to retain their religions under the dhimmi system, which conferred protected but subordinate status on Jews and Christians in exchange for a poll tax (jizya).

The Sunni-Shia Split — The Foundational Schism

The split between Sunni and Shia Islam originated immediately after Muhammad’s death, over the question of succession. Sunnis hold that the community legitimately selected Abu Bakr — Muhammad’s father-in-law and close companion — as the first Caliph (successor). Shia Muslims hold that the Prophet had designated his cousin and son-in-law Ali ibn Abi Talib as his rightful successor, and that Ali’s exclusion from leadership constituted a usurpation. The theological and political dimensions of this dispute were dramatically clarified at the Battle of Karbala (680 CE), where Ali’s son Hussein ibn Ali — the Prophet’s grandson — was killed along with most of his family by the forces of the Umayyad Caliph Yazid. For Shia Muslims, Hussein’s martyrdom at Karbala is the central event of sacred history after the Prophet’s ministry itself, commemorated annually in the mourning observance of Ashura. This schism — now 1,344 years old — continues to shape the geopolitics of the Muslim world, most visibly in the Saudi-Iranian regional rivalry.

Islam is among the most systematically structured of the world’s major religions. Its belief and practice are organised around two complementary frameworks: the Five Pillars of Islam (the required actions) and the Six Articles of Faith (the required beliefs). Together these define the minimum content of being Muslim across all major denominations.

The Five Pillars — Required Practice

• Shahada — The Declaration of Faith “Ash-hadu an la ilaha illallah, wa ash-hadu anna Muhammadan rasulullah” — “I bear witness that there is no god but God, and I bear witness that Muhammad is the messenger of God.” The Shahada is the foundational statement of Islamic identity. Its recitation with sincere belief constitutes entry into Islam. Its two clauses carry distinct theological content: the first (tawhid) asserts absolute, uncompromising monotheism — the most important single principle in Islamic theology; the second asserts Muhammad’s prophetic authority and thereby the validity of the Quran and Sunnah as sources of divine guidance.
• Salat — Five Daily Prayers Muslims are required to perform five formal prayers daily — at dawn, midday, afternoon, sunset, and night — facing the direction of the Kaaba in Mecca (the Qibla). Each prayer involves a structured sequence of standing, bowing, prostration, and sitting, accompanied by specific Quranic recitations. The prayers are preceded by ritual purification (wudu). The Friday midday prayer (Jumu’ah) includes a sermon and is performed in congregation. The prayer system structures the entire day around regular acknowledgment of God — a practice understood as both spiritual discipline and the practical demonstration of submission (the meaning of “Islam”) to divine authority.
• Zakat — Obligatory Almsgiving Muslims who possess wealth above a minimum threshold (nisab) are required to give 2.5% of their accumulated savings annually to specified categories of recipients: the poor, the indebted, travellers in need, and others. Zakat is not charity — it is a religious obligation and, in some Islamic legal frameworks, a form of taxation. It is understood theologically as a purification of wealth — acknowledging that wealth belongs ultimately to God and that the community’s collective welfare is a divine responsibility. Its annual global total is estimated at between $200 billion and $1 trillion, making it one of the world’s largest transfers of wealth.
• Sawm — Fasting During Ramadan During the lunar month of Ramadan — the ninth month of the Islamic calendar, during which the Quran was first revealed — Muslims abstain from food, drink, smoking, and sexual relations from dawn until sunset. The fast is broken each evening with iftar, traditionally beginning with dates and water, and the pre-dawn meal (suhoor) concludes the night. Ramadan is simultaneously a period of fasting, intensified prayer, Quran recitation, and communal celebration. The Night of Power (Laylat al-Qadr), occurring in the last ten nights of Ramadan, is believed to be holier than a thousand months — the night on which the first Quranic revelation descended.
• Hajj — The Pilgrimage to Mecca Every Muslim who is physically and financially capable is required to perform the Hajj — the annual pilgrimage to Mecca — at least once in their lifetime. The Hajj occurs during the Islamic month of Dhu al-Hijjah and involves a sequence of rituals over five days: circling the Kaaba seven times (tawaf), walking seven times between the hills of Safa and Marwa, standing in prayer on the plain of Arafat (the central ritual, without which Hajj is invalid), and casting stones at three pillars representing the devil. Approximately 2–3 million pilgrims perform Hajj annually, making it the largest annual human gathering on Earth. The rituals re-enact events from the lives of Ibrahim (Abraham), his wife Hajar, and his son Ismail — understood in Islam as the founders of the Kaaba.

The Six Articles of Faith — Required Belief

• Belief in God (Allah) — Tawhid The absolute oneness and uniqueness of God is the central theological principle of Islam, given the Arabic name tawhid. God has no partners, no equals, no offspring, and no physical form. The Islamic critique of Christianity is largely a critique of what Islam considers the theological compromise of tawhid in the Trinity doctrine. The 99 Names of God in Islamic theology describe divine attributes — the Merciful, the Compassionate, the Just, the Knowing — without constituting separate aspects of a multiple-personed deity.
• Belief in the Angels Angels are non-human beings created from light, without free will, whose function is to carry out God’s commands. They include Jibril (Gabriel), who delivered the Quran to Muhammad; Mikail (Michael), associated with providence; Israfil, who will blow the trumpet at the Day of Judgment; and Azrael, the angel of death. Every human being is accompanied by two recording angels who document all deeds for the Day of Judgment.
• Belief in the Revealed Books God has revealed scriptures to multiple prophets throughout history. The books acknowledged in Islam include the Tawrat (Torah, revealed to Moses), the Zabur (Psalms, revealed to David), the Injil (Gospel, revealed to Jesus), and the Quran (revealed to Muhammad). Islam holds that the earlier scriptures were authentic divine revelations but have been corrupted (tahrif) over time through human alteration — and that the Quran is the preserved, final, and uncorrupted version. This doctrine of prior corruption is the theological basis for Islam’s claim to supersede and correct Judaism and Christianity.
• Belief in the Prophets Islam recognises 124,000 prophets (in some traditions) or 25 specifically named in the Quran, including Adam, Noah, Abraham, Moses, David, Solomon, and Jesus — all considered Muslims in the sense of submitting to God, and all delivering the same essential message of monotheism. Muhammad is the “Seal of the Prophets” — the final prophet, after whom no new revelation will come. The Islamic Jesus (Isa) is a prophet and messiah but not divine — he was not crucified (according to Quran 4:157, he was made to appear to be crucified while another was substituted), was not resurrected in the Christian sense, and will return before the Day of Judgment to correct the corruptions that have accrued to his message.
• Belief in the Day of Judgment The Day of Judgment (Yawm al-Qiyamah) is the day on which all humans will be resurrected and their deeds weighed on the divine scale. The Quran describes the signs preceding the Day of Judgment in extensive detail: the Dajjal (a figure comparable to the Antichrist), the return of Jesus, the emergence of Gog and Magog (Yajuj and Majuj), and cosmic upheavals. Every individual’s Book of Deeds — recorded throughout their life by the two recording angels — will be presented. The righteous will enter Jannah (paradise); the wicked will enter Jahannam (hellfire).
• Belief in Divine Decree (Qadar) God’s complete foreknowledge and sovereignty over all events. Everything that occurs — including human choices — is within God’s knowledge and, in the majority Sunni understanding, within God’s will. The reconciliation of divine omniscience and human free will is a theological problem Islam addresses differently across its schools: Ash’ari theology (dominant in Sunni Islam) holds that God creates human actions, which humans then “acquire”; Mutazilite theology (now minority) holds that humans genuinely create their own acts; Shia theology has its own distinct position. The problem is identical in structure to that found in Christian theology on predestination.

Paradise and Hell — The Eschatological Architecture

The Quran’s descriptions of Jannah (paradise) and Jahannam (hellfire) are among the most vivid and specific in any scripture. Paradise is described as a garden with rivers of water, milk, wine (which intoxicates not), and honey; shade trees; abundant fruit; fine garments; and the companionship of the houri — often translated as “beautiful companions” or “dark-eyed maidens” (the exact nature and gender of whom is debated across Islamic scholarship and has been the subject of significant Western misrepresentation). Most significantly, paradise includes the direct vision of God — considered the supreme felicity by Islamic mystics. Hellfire is described as a place of intense heat, with its inhabitants bound in chains, drinking boiling water, and eating from the thorny tree Zaqqum. The duration of punishment in Jahannam — whether eternal for all condemned, or finite for Muslim sinners — is a debated question within Islamic theology.

Islamic theology holds that the Quran is the literal, verbatim word of God as revealed to Muhammad through the angel Jibril, and that it has been preserved perfectly without alteration — in contrast to the earlier scriptures it accuses of corruption. This claim of perfect preservation is a central theological distinction of Islam and is the subject of significant scholarly analysis, both supportive and challenging. The textual controversies documented in this chapter are active areas of academic research and are simultaneously central to both Islamic apologetics and heterodox critique.

Fig. 2 — The Birmingham Quran manuscript, radiocarbon dated to 568–645 CE — potentially predating Muhammad’s death (632 CE). Its existence confirms early Quranic writing. Questions about whether it predates or postdates the official Uthmanic compilation remain subjects of scholarly debate.

The Compilation of the Quran — From Oral Tradition to Written Text

During Muhammad’s lifetime, the Quran was transmitted primarily through oral memorisation — preserved by the huffaz (those who memorised it in full) — and written on whatever materials were available: palm leaves, flat stones, animal bones, and parchment. There was no single authoritative written compilation during the Prophet’s lifetime. After the Battle of Yamama (633 CE), in which a significant number of Quran memorisers were killed, the first Caliph Abu Bakr commissioned Muhammad’s former secretary Zaid ibn Thabit to compile the revelations into a single written document. This compilation was deposited with Hafsah, one of the Prophet’s wives.

The third Caliph Uthman ibn Affan (r. 644–656 CE) commissioned a standardised version of this text and distributed it to the major Islamic centres, ordering all other written versions to be burned. This Uthmanic recension is the version of the Quran used today. The burning of variant texts is documented in classical Islamic historical sources. Mainstream Islamic scholarship explains this as the elimination of minor scribal variations and the standardisation of a single authentic text. Critics note that the destruction of the variants makes independent verification of the standardisation process impossible.

Textual Controversies — What Has Been Documented

• The Seven Ahruf and the Qiraat — Multiple Valid Readings Classical Islamic tradition records that the Quran was revealed in “seven ahruf” — typically translated as “seven modes” or “seven dialects.” The exact meaning of ahruf is debated among Islamic scholars and has never been definitively resolved. What is documented is that there are ten (or fourteen, in some classifications) recognised variant readings of the Quran — known as the Qiraat — which differ in vowelisation, pronunciation, and occasionally in ways that affect meaning. The most widely used today is the Hafs ‘an ‘Asim reading. The Warsh ‘an Nafi’ reading is standard in North and West Africa. The differences between readings are generally minor but have occasionally been cited in theological debates about specific verses.
• The Satanic Verses Incident — A Documented Classical Controversy Classical Islamic historians — including al-Tabari and Ibn Sa’d — record an incident in which Muhammad, while reciting Surah 53 (Al-Najm), was said to have pronounced verses praising three Meccan goddesses as legitimate intercessors: “These are the exalted gharaniq [cranes], whose intercession is approved.” These verses were subsequently retracted, with the explanation that they had been inserted by Satan into the revelation. The incident — known as the “Satanic Verses” — is recorded in multiple early Islamic sources and was the theological and narrative basis for Salman Rushdie’s controversial 1988 novel. Mainstream Islamic scholarship has questioned the authenticity of these accounts and most consider them fabrications or misunderstandings. Their appearance in major classical Islamic historical texts is documented.
• The Missing Verse of Stoning — Abrogated or Suppressed? Classical Islamic jurisprudence includes stoning as a punishment for adultery (rajm) — a punishment for which there is no explicit Quranic verse. The legal basis is derived from Hadith. Multiple classical sources, however, record that there was a Quranic verse prescribing stoning — known as the “verse of stoning” (ayat al-rajm) — which was among the revelations that were abrogated (cancelled) or whose physical text was lost. Umar ibn al-Khattab, the second Caliph, is recorded in Sahih al-Bukhari as stating: “Among the things which Allah sent down was the verse of stoning… I am afraid that after a long time has passed, people will say, ‘We do not find the verse of stoning in Allah’s Book.'” This reference to a Quranic verse on stoning that does not appear in the received Quran is among the most discussed textual anomalies in Quranic studies.
• The Hadith Authenticity Problem — Fabricated Traditions The Hadith — the recorded sayings and actions of Muhammad — are the second source of Islamic law after the Quran. The canonical Hadith collections (Bukhari, Muslim, Abu Dawud, Tirmidhi, Ibn Majah, Nasai) were compiled 200–300 years after Muhammad’s death. The science of Hadith criticism (ilm al-rijal) developed sophisticated methods for evaluating the reliability of transmission chains (isnad). Despite this, all classical scholars acknowledged significant fabrication in the Hadith corpus. Imam Bukhari reportedly examined 600,000 traditions and accepted approximately 7,000 as authentic. The Hadith contain traditions that contradict each other, contradict the Quran, and in some cases reflect the political interests of the parties that produced them. The Quran-only movement (Quranists) reject the Hadith entirely on these grounds; mainstream Sunni and Shia Islam consider this position heretical.
• The Birmingham Quran — Does the Text Predate Muhammad? In 2015, radiocarbon dating of parchment fragments held at the University of Birmingham — containing Quranic text — returned a date range of 568–645 CE, with 95% probability. Muhammad’s mission began in 610 CE and ended at his death in 632 CE. The lower end of the date range potentially places the parchment before the beginning of Muhammad’s prophethood. Mainstream Islamic scholars have argued that the parchment could have been prepared before the text was written, and that the dating places the text within Muhammad’s lifetime. Some researchers have proposed that if the text predates Muhammad’s mission, it raises questions about the Quran’s claimed origin. The question is unresolved and the subject of ongoing analysis.

Archaeological investigation of Islam’s sacred sites faces a unique obstacle: the religious prohibition on non-Muslim access to Mecca and Medina, combined with the Saudi government’s large-scale construction and demolition of historical sites in these cities over the past century, has severely limited independent academic investigation of the physical evidence bearing on Islam’s earliest history. This chapter documents both what has been found and what has been made inaccessible.

Fig. 3 — Mecca as depicted in an 1850 illustration. The city’s appearance has been dramatically transformed by Saudi construction. An estimated 95% of Mecca’s millennium-old buildings have been demolished since 1985, including sites directly associated with the Prophet Muhammad and his family.

The Destruction of Islamic Heritage in Mecca and Medina

Since the 1985 expansion of the Masjid al-Haram (the Grand Mosque surrounding the Kaaba), Saudi authorities have demolished an estimated 95% of Mecca’s pre-modern structures — including buildings that Islamic tradition associated with the Prophet Muhammad, his family, and his companions. Sites destroyed include: the house of Khadijah (Muhammad’s first wife), demolished to build public toilets; the house of Abu Bakr (the first Caliph), demolished to build the Hilton Hotel; and the birthplace of Muhammad himself, now under the Maktaba Assoulet library. The Ottoman-era Ajyad Fortress, a 200-year-old landmark, was demolished in 2002 to build hotel towers. The theological justification provided by Saudi Wahhabi authorities is that veneration of historical sites constitutes a form of shirk (associating partners with God) — the gravest sin in Islamic theology. UNESCO and the Organisation of Islamic Cooperation have both expressed concern. The practical effect is that the physical environment of Islam’s foundational events has been largely erased.

The Qibla Orientation Anomaly

One of the most discussed anomalies in early Islamic archaeology concerns the orientation of the oldest surviving mosques. Muslims pray facing the Qibla — the direction of the Kaaba in Mecca. Modern mosques are oriented with GPS precision. However, several mosques from the earliest period of Islamic history — including the Quba Mosque in Medina (traditionally the first mosque ever built) and mosques in Iraq and Egypt dating to the 7th and 8th centuries CE — are oriented not toward Mecca but toward the northwest — in the direction of the Petra region of modern-day Jordan.

This observation, associated particularly with researcher Dan Gibson’s work in “Quranic Geography” (2011), has led to the proposal that early Islam’s sacred city was not the modern Mecca but Petra — a major ancient trading city in Jordan whose history aligns in some respects with descriptions of early Islamic commerce. The mainstream Islamic and archaeological response is that early mosques used different methods to calculate the Qibla direction and that errors are expected given the technology of the period. The debate continues in academic and alternative research communities. Direct archaeological investigation of the Mecca region to settle the question is not permitted.

The Black Stone — Origin and Significance

Embedded in the eastern corner of the Kaaba is the Black Stone (Al-Hajar al-Aswad) — a dark reddish-brown stone approximately 30 centimetres in diameter, now held in a silver frame. Muhammad is said to have placed it in the Kaaba’s corner himself. Islamic tradition holds that the stone descended from paradise, originally white, and was blackened by the sins of humanity. Pilgrims performing tawaf attempt to kiss it in imitation of the Prophet, who kissed it. Geological analysis of fragments and photographs suggests the stone may be a meteorite, a volcanic basalt, or a glass-bearing impactite — no definitive scientific analysis has been conducted on the stone itself. It was stolen and held by the Qarmatian sect from 930–952 CE; during this period it was broken into pieces, which were later reassembled. The stone’s pre-Islamic history in the Kaaba — which contained 360 idols before Muhammad destroyed them — is documented in Islamic sources.

The Prophet’s Tomb — The Green Dome Controversy

Muhammad is buried in Medina under what is now the Green Dome of the Prophet’s Mosque (Masjid an-Nabawi). His tomb — along with the adjacent tombs of Abu Bakr and Umar — is the second-holiest site in Islam and receives millions of pilgrims annually. Wahhabi theological authorities within Saudi Arabia have repeatedly called for the demolition of the Green Dome on the grounds that the veneration of tombs is prohibited. In 1925, Saudi forces under Ibn Saud destroyed numerous historic tombs and shrines in Mecca and Medina; the Prophet’s tomb has been spared, but the debate about its status has not been resolved. Declassified US State Department documents from 2012 (published by WikiLeaks) include Saudi clerical discussions about the planned demolition of the dome. Its continued existence reflects the political impossibility of demolishing what is universally regarded as the Prophet’s resting place, more than the theological consensus of those in authority.

Alongside the legal, doctrinal, and ritual Islam documented in Chapters I and II lies a rich, ancient, and in many contexts persecuted tradition of Islamic mysticism known as Sufism (tasawwuf). Sufism holds that the outward practice of Islam — the Five Pillars, adherence to Islamic law (Sharia) — is the necessary but not sufficient expression of faith. The inner dimension of Islam — the purification of the self, the direct experiential knowledge of God (marifah), and ultimately the annihilation of the ego in divine union (fana) — constitutes the deepest level of the religion, accessible through spiritual discipline, meditation, and the guidance of a master (shaykh).

Fig. 4 — The Mevlana Museum, Konya, Turkey — tomb of Jalal ad-Din Rumi, the 13th-century Sufi poet and founder of the Mevlevi Order. Rumi’s Masnavi is considered by many Islamic scholars the greatest work of mystical poetry in any language. His tomb receives over 2 million visitors annually.

The Inner and Outer Dimensions — Zahir and Batin

The Sufi tradition distinguishes between the zahir (the outward, exoteric dimension of religion) and the batin (the inward, esoteric dimension). This distinction has deep Quranic roots: the Quran itself speaks of al-Kitab al-Maknun — the “hidden book” — and refers to an “inner knowledge” (ilm ladunni) granted directly by God. Sufi masters teach that the Quran has multiple layers of meaning — a surface (zahir) meaning accessible to all and a hidden (batin) meaning accessible only to those who have undergone spiritual purification. This hermeneutical approach — which has produced centuries of Quranic allegorical commentary — is rejected by literalist Salafi and Wahhabi Islam as innovation (bidah) or worse.

The Major Concepts of Sufi Esoteric Teaching

• Fana — Annihilation in God The Sufi concept of fana describes the dissolution of the individual ego in the experience of divine presence — a state in which the distinction between the worshipper and the worshipped temporarily ceases. This concept, which has structural parallels to mystical experiences in Hindu Advaita Vedanta and Christian mysticism, is the endpoint of the Sufi path. The 9th-century Sufi Al-Hallaj is the most famous case of its dangerous implications: he reportedly declared “Ana al-Haqq” — “I am the Truth/Reality” (one of the Names of God) — while in a state of divine union. He was executed in Baghdad in 922 CE for heresy. His case documents both the height of Sufi mystical aspiration and the institutional violence it attracted.
• The Inner Jihad — Al-Jihad al-Akbar A Hadith attributed to Muhammad, though contested in its chain of transmission, states that upon returning from battle, he told his companions: “We have returned from the lesser jihad (al-jihad al-asghar) to the greater jihad (al-jihad al-akbar).” When asked what the greater jihad was, he replied: “The jihad against oneself.” This concept — that the primary spiritual struggle in Islam is the internal battle against the ego, desires, and spiritual shortcomings — is central to Sufi practice. It does not negate the concept of armed struggle in Islamic law but reframes the entire religious life as a sustained inner combat. The Hadith’s authenticity is disputed by Salafi scholars, who use the dispute to argue against the Sufi interpretation of jihad. Its acceptance or rejection is itself a marker of the division between esoteric and literalist Islam.
• Rumi and the Poetry of Divine Love Jalal ad-Din Muhammad Rumi (1207–1273 CE) is the most widely read poet in the world by some measurements — his works are bestsellers in the United States as well as the Muslim world. His Masnavi — a six-volume spiritual epic in Persian — contains Sufi teaching in the form of stories, parables, and poetry that addresses the soul’s longing for its divine origin, the nature of love as the primary cosmological force, and the path of return through spiritual discipline and surrender. Rumi is the central figure of the Mevlevi Order, whose devotional practice includes the Sema — the whirling meditation that has given rise to the popular image of the “whirling dervish.” The Mevlevi Order was banned in Turkey from 1925 to 1954 as part of Atatürk’s secularisation programme.
• Ibn Arabi — The Greatest Sheikh and the Unity of Being Muhyiddin Ibn Arabi (1165–1240 CE), known as al-Shaykh al-Akbar (the Greatest Sheikh), is the most systematically sophisticated of the Sufi metaphysicians. His doctrine of Wahdat al-Wujud — the Unity of Being — holds that all existence is a manifestation of the one divine Reality, and that the apparent multiplicity of creation is a self-disclosure (tajalli) of God’s infinite attributes. This position — which collapses the distinction between Creator and creation into a metaphysical unity — was condemned as heretical by major jurists of his time and continues to be rejected by Salafi Islam. It is also, simultaneously, the most philosophically sophisticated metaphysical system produced in the Islamic world, and has influenced Jewish Kabbalah, Christian mysticism, and South Asian Islamic thought.
• Ismailism and the Batini Tradition — The Hidden Imam and Esoteric Interpretation Ismaili Islam — a branch of Shia Islam — holds that the Quran has a hidden inner meaning (batin) that is revealed only by the living Imam, the descendant of Ali and Fatimah who carries the authority of Muhammad’s lineage. For Ismailis, the Imam is the guardian of esoteric knowledge, and the community’s relationship to truth is mediated through his living authority rather than through textual scholarship. The Fatimid Caliphate (909–1171 CE) — which at its height controlled North Africa, Egypt, Sicily, and parts of the Levant — was an Ismaili state that established the Al-Azhar institution in Cairo (originally as an Ismaili teaching institution; later converted to Sunni use). The Aga Khan, the current Ismaili Imam, leads a community of approximately 15 million and is among the wealthiest individuals in the world.

The institutional and political controversies of Islam are extensive, ongoing, and consequential. They include fourteen centuries of sectarian violence, the emergence of modern jihadist movements, the treatment of religious minorities and women under Islamic law in multiple jurisdictions, and the ongoing contest between reformist, traditionalist, and extremist interpretations of the religion for the allegiance of 1.9 billion people. All of these are documented in this chapter as history, not as theological argument.

The Sunni-Shia Conflict — Fourteen Centuries of Violence

The Sunni-Shia divide, originating in the succession dispute documented in Chapter I, has produced recurring cycles of violence across Islamic history. The most significant contemporary expression is the Saudi-Iranian rivalry — a geopolitical competition between the world’s pre-eminent Sunni (Saudi) and Shia (Iranian) powers — which has fuelled proxy wars in Yemen, Syria, Lebanon, Bahrain, and Iraq. Sectarian violence has killed hundreds of thousands in Iraq alone since 2003. The Islamic State (ISIS/ISIL/Daesh), which declared a “Caliphate” in 2014, explicitly framed Shia Muslims as apostates deserving death — a position it acted on through systematic massacres documented by the United Nations. The Yazidi genocide (2014), in which ISIS killed an estimated 5,000 Yazidis and enslaved 7,000 Yazidi women and girls, is the most extensively documented instance of religiously motivated mass atrocity in the 21st century.

Extremism and Terrorism — The Documented Record

• Al-Qaeda and the September 11 Attacks On September 11, 2001, Al-Qaeda operatives hijacked four aircraft and killed 2,977 people in New York, Virginia, and Pennsylvania — the deadliest terrorist attack in history. Al-Qaeda, founded by Osama bin Laden in Afghanistan, articulated a jihadist ideology drawing on Salafi theology to justify attacks on the “far enemy” (the United States and Western powers) as a means of ending Western influence in Muslim-majority countries and overthrowing “apostate” Muslim governments. The 9/11 Commission Report and subsequent intelligence investigations document the planning, financing, and execution of the attacks in detail. The theological question of whether Al-Qaeda’s interpretation of jihad is compatible with mainstream Islamic law — the answer of virtually every Islamic scholarly body is unambiguously no — does not change the documented fact that the attacks were planned and executed by individuals acting under an Islamic religious framework.
• ISIS — The Caliphate and Its Documented Crimes The Islamic State of Iraq and Syria (ISIS) controlled territory in Iraq and Syria from approximately 2013 to 2019, at its peak governing approximately 8 million people. It administered its territory according to a specific interpretation of Islamic law that included public execution, amputation, crucifixion, stoning, and slavery — all presented as restoration of authentic early Islamic practice. UN investigations documented genocide against Yazidis, mass executions of Shia Muslims, destruction of pre-Islamic and non-Sunni Islamic heritage sites, and systematic sexual slavery. The defeat of ISIS’s territorial caliphate has not ended its global franchise, which has carried out attacks across Europe, Africa, and Asia.
• Apostasy and Blasphemy Laws — The Institutional Enforcement of Belief In multiple countries with majority Muslim populations and Islamic legal frameworks, apostasy (leaving Islam) and blasphemy (insulting Islam or the Prophet) are criminal offences carrying punishments up to death. Countries with the death penalty for apostasy as of 2025 include: Saudi Arabia, Qatar, Yemen, Iran, Afghanistan (under Taliban governance), Mauritania, and others. The apostasy and blasphemy laws are supported by a reading of the Hadith literature — there is no Quranic verse explicitly prescribing death for apostasy, which has led reformist Muslims to argue the laws have no valid scriptural basis. The laws are enforced at state level and also through vigilante violence in communities where state enforcement is absent. Documented victims include Ahmadi Muslims in Pakistan, Christian converts from Islam across the Middle East and South Asia, and individuals accused of blasphemy on social media.
• Women Under Islamic Law — The Documented Range The status of women under Islamic law varies dramatically across jurisdictions and interpretive frameworks. At one end: Saudi Arabia did not permit women to drive until 2018, still requires a male guardian’s permission for many legal acts, and enforces strict gender segregation; Afghanistan under Taliban governance has banned women from secondary and higher education and most employment. At the other end: Indonesia, the world’s most populous Muslim-majority country, has had a female head of state (Megawati Sukarnoputri, 2001–2004) and active female political participation; Tunisia and Morocco have implemented significant legal reforms expanding women’s rights within Islamic frameworks. The debate about the compatibility of women’s rights with Islamic law is one of the most active internal debates within the Muslim world, with significant scholarly weight on both the traditional-restriction and the reformist-equality sides.

As of 2026, Islam is simultaneously the world’s fastest-growing religion, a religion experiencing severe internal ideological conflict, the civilisational foundation of 49 nation-states, the focus of intense Western political and security attention since 2001, and a tradition producing active reform movements in multiple countries and communities that are challenging centuries of traditional interpretation. The following documents its contemporary status.

The Islamic Republic of Iran, established 1979, represents the most significant experiment in political Islam in the modern era — a theocratic state governed by Shia Islamic jurisprudence. Its model has influenced Islamist movements globally, including those that consider it a model and those that consider it a warning.

Demographic Reality — The Fastest-Growing Religion

Islam’s global growth is driven primarily by demographics rather than conversion: Muslim-majority populations have higher birth rates and younger median ages than the global average. Pew Research projects that Islam will equal Christianity in global adherents by approximately 2070 and surpass it in the following decades. Sub-Saharan Africa is the fastest-growing Muslim region. Islam is the fastest-growing religion in Europe through immigration and a higher birth rate among Muslim immigrant communities, generating significant political response across European democracies. The United States has approximately 3.45 million Muslim residents (about 1% of population), a community that is among the most economically integrated Muslim communities in any Western country.

Islamic Reform Movements — The Internal Debate

The contest between reformist and traditionalist interpretations of Islam is among the most consequential debates of the 21st century. Reform-oriented scholars and movements argue that the traditional corpus of Islamic law — developed primarily in the 8th to 10th centuries CE — reflects the historical context of its formation rather than timeless divine prescription, and that a historically aware and contextually sensitive interpretation of the Quran and Hadith can produce Islamic frameworks compatible with human rights, democracy, gender equality, and religious pluralism. Traditional and Salafi/Wahhabi scholars argue that departing from the established corpus constitutes dangerous innovation and that the solution to the Muslim world’s problems is greater adherence to, rather than reinterpretation of, the tradition.

Islam and the Other Abrahamic Faiths — The Theological Triangle

Islam presents itself as the final and corrective revelation in the sequence that includes Judaism and Christianity. Its theology is therefore defined in part by its relationship to these traditions: affirming the prophetic status of Moses and Jesus while asserting that their messages were corrupted and that Muhammad’s revelation restores and completes what they began. Jewish and Christian theology generally do not reciprocate this acknowledgment — neither recognises Muhammad as a prophet. The resulting theological triangle — three traditions claiming descent from Abraham, each making exclusive truth claims while overlapping significantly in content — is the foundational structure of Western religious history and its continuing conflicts.

The Open Questions — Evidentiary Assessment

Archival Status and Classification

Islam is assessed by this Directorate as the most rapidly evolving major civilisational force of the 21st century — a tradition simultaneously producing the world’s fastest demographic growth, the most active internal theological debate, the most consequential geopolitical conflicts, and some of the most profound mystical literature in any language. It contains, in the Sufi tradition, a path of inner transformation that its mainstream orthodoxy sometimes persecutes; a legal tradition of extraordinary sophistication that its critics frequently reduce to its harshest contemporary applications; a text — the Quran — whose transmission history is more documentably traceable than that of the Bible; and a global community whose internal diversity is vastly underrepresented by the fraction of it that generates violence.

The suppression of the Sufi and esoteric layer — the destruction of shrines, the execution of mystics, the banning of orders — parallels the suppression of Gnostic Christianity documented in the companion file. In both traditions, the institutionalised exoteric form has at various points turned its authority against the inner-directed mystical form that claims to represent the deepest level of the same revelation. The pattern is documented. The Directorate declines to adjudicate between them.

The building is the material record of the contest between Christianity and Islam for the same sacred space across fifteen centuries. The calligraphy is Arabic. The mosaics beneath the plaster are Christian. Both are still present.
