24. An-Nur

An-Nur ('The Light'), 64 Medinan verses, legislates on modesty, lowering the gaze and covering, and on the penalties and procedures in cases of accusation. It vindicates Aisha against slander (the ifk, 24:11-20) and contains the celebrated Verse of Light, likening God's light to a lamp in a niche (24:35).

The account of the ifk, the slander against Aisha that circulated in Medina after she was inadvertently left behind during a campaign and returned separately in the company of a companion, is narrated at length in the hadith collections of al-Bukhari and Muslim as well as summarised in the surah's own verses, which describe a month of anguish before revelation declared her innocence and prescribed severe punishment for those who levelled the accusation without the required four witnesses (24:11-20). This episode is treated in Islamic legal history as foundational for the law of qadhf, false accusation of unchastity, requiring four eyewitnesses to a specific act, a standard commentators note makes successful prosecution of such accusations extremely difficult and was read by classical jurists as deliberately protective of reputation. The Verse of Light (24:35), likening God's guidance to a lamp within a glass within a niche, lit from a blessed olive tree, became one of the most commented-upon single verses in the Quran, generating an entire genre of mystical commentary, most famously al-Ghazali's Mishkat al-Anwar, reading the verse as a map of levels of illumination in the human soul.

An-Nur legislates household etiquette in some detail, instructing believers to seek permission and greet the occupants before entering any home but their own (24:27-29), and setting out when even children and servants within a household must seek permission before entering a parent's or employer's private room (24:58-59), provisions classical and later commentary treat as an early scriptural basis for domestic privacy distinct from, though related to, the surah's better known material on modesty in dress and public conduct.

The surah also instructs the community to arrange marriage for the unmarried among them and for capable slaves seeking to marry, promising that God will provide for the poor among them from His bounty (24:32-33), a passage later Islamic legal and social writing cites as scriptural encouragement toward communal responsibility for facilitating marriage rather than treating it as a purely private, individual arrangement, and as grounds for opposing economic hardship as a bar to marriage. Both provisions are frequently cited together in modern discussions of Islamic family and social law as evidence that the surah addresses practical household and communal arrangement alongside its better known material on modesty and testimony.
