وَعْدَ ٱللَّهِ ۖ لَا يُخْلِفُ ٱللَّهُ وَعْدَهُۥ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ
3:195; 39:21.
Commentary:
The reference in the words, "Allah has made this promise," is to the Divine decree alluded to in the words "that Allah might accomplish the thing that was decreed" (8:43) used with reference to the Battle of Badr.
