Surah Aal-E-Imran Ayahs #129 Translated in English

Yes, if you remain patient and conscious of Allāh and they [i.e., the enemy] come upon you [attacking] in rage, your Lord will reinforce you with five thousand angels having marks [of distinction]."

And Allāh made it not except as [a sign of] good tidings for you and to reassure your hearts thereby. And victory is not except from Allāh, the Exalted in Might, the Wise -

That He might cut down a section of the disbelievers or suppress them so that they turn back disappointed.

Not for you, [O Muḥammad, but for Allāh], is the decision whether He should [cut them down] or forgive them or punish them, for indeed, they are wrongdoers.

And to Allāh belongs whatever is in the heavens and whatever is on the earth. He forgives whom He wills and punishes whom He wills. And Allāh is Forgiving and Merciful.
