THE OPINIONS of the earliest commentators are divided as to whether this surah - also called Ad-Dahr ("Time" or "Endless Time") after a word occurring in the first verse - belongs to the Mecca or the Medina period. Many authorities of the second generation - among them Mujahid, Qatadah, Al-Hasan al-Basri and 'Ikrimah (all of them quoted by Baghawi) - hold the view that it was revealed at Medina.
HAS THERE [not] been an endless span of time1 before man [appeared - a time] when he was not yet a thing to be thought of?2
