At-Takwir ('The Overthrowing'), 29 Meccan verses, paints the unmaking of the cosmos, the sun folded up, the stars falling, the seas boiling, and the buried infant girl asked for what crime she was killed (81:8-9), a rebuke of pre-Islamic female infanticide. It affirms the Quran as the word brought by a noble messenger. The surah's condemnation of the pre-Islamic practice of burying infant daughters alive, asking 'for what crime she was killed' (81:8-9), is cited by both classical and modern commentators as direct Quranic evidence that female infanticide (waad al-banat) was a real, if not universal, practice among some pre-Islamic Arabian tribes, generally connected in the historical literature to economic hardship and social anxieties over daughters rather than to any single uniform custom across Arabia. Its opening list of cosmic unravelling, the sun folded up, the stars falling, the mountains set moving, gives Quranic apocalyptic imagery some of its most frequently quoted individual lines.
The surah's closing affirmation that the Quran came through 'a noble messenger,' possessed of power and trust before the throne (81:19-21), read together with its earlier denial that the Prophet is a madman or that his vision was anything but a clear sighting of the angel on the horizon (81:22-23), directly answers charges classical commentators report as current in early Mecca. Some early exegetes read the 'noble messenger' here as referring to Gabriel rather than to Muhammad himself, a genuine point of classical interpretive division the surah's own wording does not settle beyond doubt.
