81. Surah At-Takwir (التكوير), the 81st chapter of the Qur'an, is a highly dramatic and visually arresting Makkan Surah composed of 29 verses. Its title translates to "The Folding Up", "The Wrapping", or "The Shrouding", referring to the cosmic rolling up of the sun's immense light at the end of time. Renowned for its cinematic pacing, the Surah uses a rapid, thunderous cadence of hypothetical clauses ("When the sun is rolled up... when the stars fall...") to paint a terrifying picture of universal deconstruction, before shifting to validate the celestial authority of the Qur'anic revelation.
