This beautiful Sūra was the last of the Sūras to be revealed as a whole, though the portion of the verse 5:3, “This day I have perfected your religion for you”, etc., contains probably the last words of the Qur-ān to be revealed.
The date of this Sūra was only few months before the passing away of the holy Prophet from this world, Rabi’ I, A.H. 11. The place was either the precincts of Mecca at his Farewell Pilgrimage, Ẓulḥijja, A.H. 10, or Medīna after his return from the Farewell Pilgrimage.
Victory is the crown of service, not an occasion for exultation. All victory comes from the help of God.

C. 290 | [110:1-3] For that which is right the help of God is ever nigh, and victory! When the spirit of men is stirred, they come to the flag of faith in troops and battalions. They are to be welcomed: but Praise and Glory belong to God: to Him we humbly turn and pray for Grace: for He is Oft-Returning in Grace and Mercy.
