Islam

There is no god but God — a sentence simple enough to say in a breath, total enough to reorder a civilization.

Origins and History

Islam began in the merchant city of Mecca in the early seventh century, when Muhammad ibn Abdullah — a respected trader given to solitary retreats — reported that the angel Gabriel had commanded him to recite. The revelations that followed over twenty-three years became the Quran. Muhammad preached uncompromising monotheism to a polytheist city that profited from its shrines, and the message was not welcome; in 622 he and his followers migrated to Yathrib (Medina), an event — the Hijra — so decisive that the Islamic calendar counts from it. By his death in 632, most of Arabia had accepted Islam.

What happened next has few parallels. Within a century, Muslim rule stretched from Spain to the Indus. The community split early over succession: those who held that leadership belonged to the Prophet's family, beginning with his cousin and son-in-law Ali, became the Shia; the majority, who accepted the elected caliphs, became the Sunni. The Abbasid centuries made Baghdad a world capital of science, philosophy, and translation — Aristotle survived for the Latin West largely through Arabic. Later empires (Ottoman, Safavid, Mughal) carried the faith to its modern breadth. Today Islam is the world's second-largest religion, with about two billion adherents, most of them living east of the Arab world in South and Southeast Asia.

Core Beliefs

The heart of Islam is tawhid — the absolute oneness and uniqueness of God (Allah, simply Arabic for "the God"). Islam positions itself not as a new religion but as the restoration of the primordial monotheism preached by every prophet: Adam, Noah, Abraham, Moses, and Jesus among them, with Muhammad as the final "seal of the prophets." Jesus is honored as Messiah and prophet, born of a virgin, but not as divine — associating partners with God (shirk) is the one unforgivable sin. In the vocabulary of comparative religion, Islam is monotheism at its most austere; where Henotheism describes devotion to one god among many, tawhid denies that there is any "many" for God to be among.

Muslims affirm six articles of faith: God, His angels, His revealed books, His messengers, the Day of Judgment, and divine decree. Eschatology is vivid and central — resurrection, judgment, paradise, and fire — continuing the apocalyptic inheritance that runs from Zoroastrianism through Judaism and Christianity into the Quran. Humanity is not fallen but forgetful; the human problem is ghafla, heedlessness, and the remedy is remembrance (dhikr).

Practices

Practice rests on the Five Pillars. The shahada — testifying that there is no god but God and Muhammad is His messenger — makes one a Muslim. Salat, ritual prayer five times daily facing Mecca, punctuates every day with prostration. Zakat, obligatory almsgiving of roughly 2.5 percent of accumulated wealth, builds justice into worship. Sawm, the dawn-to-dusk fast through the month of Ramadan, disciplines the body and ends in the festival of Eid al-Fitr. And hajj, the pilgrimage to Mecca required once in a lifetime of those able, gathers millions annually into a single white-garmented humanity.

Beyond the pillars, Islamic law (sharia, interpreted through the schools of fiqh) shapes diet, finance, family, and ethics, while Sufism — the tradition's mystical stream — pursues the direct experience of God through chant, poetry, and the master-disciple path, giving the world Rumi, al-Ghazali, and the whirling dervishes.

Sacred Texts

The Quran is, for Muslims, the literal speech of God — not inspired writing about God, but God's own words in Arabic, which is why translation is always interpretation and why recitation is an art form of enormous prestige. Its 114 suras are arranged roughly by length, not chronology. Alongside it stands the hadith literature: reports of the Prophet's words and deeds, sifted by medieval scholars into canonical collections (Bukhari and Muslim foremost among the Sunni six), which together with the Quran ground the sunnah, the prophetic example that observant Muslims pattern their lives on.

Major Branches

The Sunni–Shia divide began as a succession dispute and deepened at Karbala in 680, where the Prophet's grandson Husayn was killed — a martyrdom Shia Muslims still mourn annually at Ashura. The nineteenth-century messianic ferment within Shia Islam also became the seedbed of the Bahá'í Faith, which emerged from Iranian Islam but understands itself as an independent religion.
