4:23 Forbidden to you are your mothers, your daughters, your sisters, your paternal aunts and maternal aunts, your brother's daughters, your sister's daughters, your mothers who have given suck to you, your suckling sisters, your wives mothers, and your stepdaughters who are in your care from your wives with whom you have lain, but if you have never lain with them it is no fault in you. (Also forbidden to you) are the wives of your sons who are of your loins, and to take to you two sisters together unless it is a thing of the past. Allah is the Forgiver and the Most Merciful.
4:24 And (forbidden to you) are married women, except those whom your right hand owns. Such Allah has written for you. Lawful to you beyond all that, is that you can seek using your wealth in marriage and not fornication. So whatever you have enjoyed from them give them their obligated wage. And there is no fault in you in what ever you mutually agree after the obligation. Allah is the Knower, the Wise.
