Al-Mujadila 58:21

Kataba Allahu laaghlibanna anawarusulee inna Allaha qawiyyun AAazeez

Allāh has written [i.e., decreed], "I will surely overcome, I and My messengers." Indeed, Allāh is Powerful and Exalted in Might.

Allah has written (in His pre-destined decree), “I will certainly prevail, both I and My messengers.” Surely Allah is All-Strong, All-Mighty.
