Surat An-Nasr (The Divine Support)|سورة النصر|

In this Surah Allah has informed His Rasool (pbuh) that when Islam attained complete victory in Arabia and the people started entering Allah's religion (Islam) in great numbers, it would mean that the mission for which he was appointed in this world, had been fulfilled. He was then enjoined to busy himself in praising and glorifying Allah by Whose bounty he had been able to accomplish such a great task, and should implore Him to forgive whatever failings and frailties he might have shown in the performance of the service.
