Period of Revelation
Its subject matter bears full evidence that it was revealed in the earliest period at Makkah. If this Surah is read together with the two Surahs preceding it, namely Al-Qiyaamah and Ad-Dahr, and the two Surahs following it, namely An-Naba and An-Nazi`aat, it becomes obvious that all these Surahs are the Revelations of the same period, and they deal with one and the same theme, which has been impressed on the people of Makkah in different ways.
