Surah Al Nasr
This beautiful Surah was the last of the Surahs to be revealed as a whole, though the portion of the verse 5:5, "This day have I perfected your religion for you" etc., contains probably the last words of the Qur'an to be revealed.
The date of this Surah was only a few months before the passing away of the Holy Prophet from this world, Rabi'i I, A.H. 11. The place was either the precincts of Makkah at his Farewell Pilgrimage, Dhu al Hijjah, A.H. 10, or Madinah after his return from the Farewell Pilgrimage.
