Circumstances of Revelation
Place: Mecca or Medina; the sūrah could have been revealed in either. Some narrations from the Imams support Medina. → Introduction
The occasion: The Prophet is reported to have said that he saw in a dream the Umayyads ascending his pulpit, which distressed him greatly, and God then revealed this sūrah. Al-Mizan: this means God comforted him with the Night of Destiny, better than a thousand months, the thousand months being the duration of Umayyad rule; many Shia narrations from the Imams express this meaning. These are the narrations that point to Medina. → Narrations
