The chapters are not arranged by date. The broad Meccan and Medinan phases help explain the changes in subject and tone, though the exact sequence is disputed.
The words traditionally identified as the Quran’s first revelation appear in chapter 96. The book itself opens with a seven-verse prayer, followed by its longest chapter, which includes laws for an established community. Its 114 chapters, called suras, run roughly from long to short. A first-time reader meets much of the later material before the early preaching.
The standard Muslim account places the first revelation around 610 CE. Muhammad, a merchant in Mecca, is about forty when the angel Gabriel appears to him in a cave outside the city. The cave scene and his wife Khadija’s reassurance come from later reports, including Sahih al-Bukhari 3. The Quran gives the command to read or recite, but does not tell that scene as a continuous story.
Many suras assigned to early Mecca are short and sharply rhymed. They announce one God, resurrection, and an accounting of every deed. Rain, livestock, sleep, and the growth of a human being become evidence of the creator’s care. The accusations are often specific: neglecting orphans, refusing to feed the poor, hoarding wealth, killing children.
The earlier prophets appear in recurring episodes. Moses confronts Pharaoh. Abraham challenges idols and, elsewhere, raises the sanctuary with Ishmael. Mary gives birth beneath a palm tree; Jesus speaks from the cradle and heals. The Quran calls him Messiah and prophet while rejecting divine sonship. It presents itself as confirming earlier revelation and judging disputes about it.
In the traditional chronology, Muhammad preaches in Mecca until the migration to Medina in 622. This move, the hijra, supplies the starting year of the Muslim calendar. In Medina he leads a religious and political community. The distinction helps explain the text, but it does not date every verse: scholars disagree about particular passages, and some suras contain material assigned to different periods.
The Medinan material includes Ramadan fasting, required giving, marriage and divorce, inheritance, contracts, punishments, and war. It addresses disputes with Jews, Christians, polytheists, and people described as hypocrites within the community. The subject can change from theology to a household rule within a few verses.
The fighting passages vary in scope. Some prohibit aggression or require protection for an enemy seeking refuge. Others command fighting polytheists or People of the Book, particularly Jews and Christians. Later jurists disagreed about the relationship between these commands. Some invoked abrogation, the view that a later revelation replaces an earlier rule.
The traditional account ends with Muhammad’s death in 632, after his return to Mecca and the removal of its sanctuary’s idols. The Quran does not end there. It moves among divine commands, prayers, stories, questions, and replies to opponents. Much of it addresses a listener directly.
Judgment includes bodily resurrection, paradise, and hell. The descriptions are concrete: gardens, shade, food and drink, fire and boiling water. Sura 47:15 puts the two destinations in the same verse.
The promises of mercy are just as explicit. Sura 39:53 tells people who have wronged themselves not to despair of forgiveness. The next verse calls them to repent and surrender before punishment comes.
