Surah 4

Surah 4:24

"And (also forbidden to you are) married women, except what your right (hands) own. (This is) a written decree of God for you. (All women) beyond that are permitted to you to seek (to obtain) by means of your wealth, taking (them) in marriage, not in immorality. So (because of) what you enjoy from them in this way, give them their marriage gifts as an obligation. (There is) no blame on you in anything you may give them by mutual agreement beyond this obligation. Surely God is knowing, wise."
