4:24And all married women, except those you rightfully possess. This is God’s decree, binding upon you. Permitted for you are those that lie outside these limits, provided you seek them in legal marriage, with gifts from your property, seeking wedlock, not prostitution. If you wish to enjoy them, then give them their dowry—a legal obligation. You commit no error by agreeing to any change to the dowry. God is All-Knowing, Most Wise.
