Quran 66:2 — Prohibition (Al-Tahreem)

GOD has decreed for you the laws dealing with your oaths. GOD is your Lord, and He is the Omniscient, Most Wise.

[66:1] O you prophet, why do you prohibit what GOD has made lawful for you, just to please your wives? GOD is Forgiver, Merciful.*

[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."
