Al-Ahzab 33:24

Liyajziya Allahu assadiqeenabisidqihim wayuAAaththiba almunafiqeena inshaa aw yatooba AAalayhim inna Allaha kanaghafooran raheema

That Allāh may reward the truthful for their truth and punish the hypocrites if He wills or accept their repentance. Indeed, Allāh is ever Forgiving and Merciful.

(All this happened) so that Allah may give reward to the truthful ones for their truthfulness, and punish the hypocrites, if He so wills, or accept their repentance. Surely, Allah is Most-Forgiving, Very- Merciful.
