Mohammed's Sex Entitlement

Mohammed can have sex with

1. his lawful wives (bride price paid);
2. slave girls (what his right hand possessed);
3. daughters of Mohammed's uncles and aunts, both paternal and maternal who had migrated with him;
4. any woman believer who she give herself to Mohammed and if Mohammed desire to take her in marriage (Mohammed-only privilege).

Prophet, we have made lawful for you your wives whom you have given their dowry, slave girls whom God has given to you as gifts, the daughters of your uncles and aunts, both paternal and maternal, who have migrated with you. The believing woman, who has offered herself to the Prophet and whom the Prophet may want to marry, will be specially for him, not for other believers. We knew what to make obligatory for them concerning their wives and slave girls so that you would face no hardship (because we have given distinction to you over the believers). God is All-forgiving and All-merciful.
You may refuse whichever (of the woman who offer themselves to you) as you want and accept whichever of them you wish. There is no blame on you if you marry (one whom you had refused previously). This would be more delightful for them. They should not be grieved but should be happy with whatever you have given to every one of them. God knows what is in your hearts. God is All-knowing and All-forbearing.
Besides these, other women are not lawful for you to marry nor is it lawful for you to exchange your wives for the wives of others (except for the slave girls), even though they may seem attractive to you. God is watchful over all things. (33:50-52 Muhammad Sarwar version)
