Quran 66:4 — Prohibition (Al-Tahreem)

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.

[66:3] The prophet had trusted some of his wives with a certain statement, then one of them spread it, and GOD let him know about it. He then informed his wife of part of the issue, and disregarded part. She asked him, "Who informed you of this?" He said, "I was informed by the Omniscient, Most Cognizant."

[66:5] 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.
