Quran 66:5 — Prohibition (Al-Tahreem)

If he divorces you, his Lord will substitute other wives in your place who are better than you; submitters (Muslims), believers (Mu'mens), obedient, repentant, worshipers, pious, either previously married, or virgins.

[66:4] If the two of you repent to GOD, then your hearts have listened. But if you band together against him, then GOD is his ally, and so is Gabriel and the righteous believers. Also, the angels are his helpers.

[66:6] O you who believe, protect yourselves and your families from the Hellfire whose fuel is people and rocks. Guarding it are stern and powerful angels who never disobey GOD; they do whatever they are commanded to do.
