﴿ قُلْ يَوْمَ ٱلْفَتْحِ لَا يَنفَعُ ٱلَّذِينَ كَفَرُوٓا۟ إِيمَٰنُهُمْ وَلَا هُمْ يُنظَرُونَ ﴾

“Say: “On the Day of the Final Decision, their [newly-found] faith will be of no use to those who [in their lifetime] were bent on denying the truth, nor will they be granted respite!” –”

(Say) O Muhammad to Banu Khuzaymah and Banu Kinanah: (On the day of the victory) of the conquest of Mecca (the faith of those who disbelieve) i.e. Banu Khuzaymah ((and who then will believe) will not avail them) from being killed, (neither will they be reprieved) from being sentenced to death.
