Overview
Islam, from the Arabic root s-l-m (“peace, surrender”), is the final expression of monotheism in the Abrahamic lineage. At its heart lies the Qur’an, believed to be the literal, uncreated Word of God (Allah) delivered by the angel Gabriel to Muhammad ibn Abdullah between 610 and 632 CE. Muslims view the Qur’an as the culminating scripture that confirms and corrects earlier revelations (Torah, Psalms, Gospels). Alongside the Qur’an, the Hadith—authenticated sayings and actions of the Prophet—form the sunnah, the living model that translates divine command into daily practice. Together they shape a comprehensive path (shariʿa) governing ethics, ritual, law, and spirituality.
The Muslim worldview pivots on tawḥīd, the uncompromising oneness of God, which engenders a cosmos of purpose and moral accountability. Humanity’s role is that of khalīfa (viceregent), entrusted with stewardship of creation. Salvation is achieved not through vicarious atonement but through mindful surrender (islām) expressed in the Five Pillars: witness of faith, ritual prayer five times daily, almsgiving, fasting the month of Ramadan, and pilgrimage to Mecca once in a lifetime if able. These pillars demarcate a trans-national ummah whose demographic arc stretches from Morocco to Mindanao, from Lagos to London, making Islam the world’s most ethnically diverse religion.
Background
Pre-Islamic Arabia was a mosaic of polytheistic tribes, Jewish agriculturalists, Christian ascetics, and Zoroastrian traders. Mecca, home to the Kaʿba built—Muslims believe—by Abraham and Ishmael, was already a pilgrimage node. Into this milieu was born Muhammad (c. 570 CE) of the Quraysh tribe. Orphaned early, he became a trusted caravan manager for the wealthy widow Khadija, later his first convert. At age 40 he received the initial revelation: “Recite in the name of your Lord who created.” His monotheistic preaching threatened Meccan mercantile elites, precipitating the Hijra (622 CE) to Medina, where he established the first Islamic polity. Eight years later he returned to Mecca, cleansed the Kaʿba of idols, and died in 632 CE without naming a successor. The subsequent Rashidun, Umayyad, and Abbasid caliphates carried Islam from Iberia to the Indus within a century, fusing Greco-Hellenic, Persian, and Indian currents into a golden age of science, medicine, and philosophy. Over fourteen centuries, the faith ramified into Sunni (≈85 %), Shiʿa (≈15 %), and numerous mystical or rationalist schools, each negotiating the balance between revelation and reason.

Impact
Islam’s intellectual renaissance transmitted Aristotle to medieval Europe via Averroes and Avicenna, giving scholastic theology its vocabulary of being and essence. Islamic finance—banning usury and emphasizing risk-sharing—now oversees >$3 trillion in assets, pioneering green sukuk for climate adaptation. The Qur’anic injunction to “seek knowledge” has produced the world’s highest female STEM graduates per capita in Jordan and Brunei, while micro-zakat funds lift millions out of poverty. Culturally, the adhān (call to prayer) rings out as sonic architecture in cities from Detroit to Jakarta, and Ramadan nights transform global markets into luminous festivals of generosity. Politically, Islam inspires liberation theologies, environmental ethics, and democratic experiments—Tunisia’s 2014 constitution cites “maqaṣid al-shariʿa” (higher objectives of law) to balance civil rights with public morality. Yet colonial legacies and sectarian rivalries also fuel conflicts, reminding the ummah that the greater jihad—struggle against inner injustice—remains perpetual.
