Al-Ahzab 33:50 يا ايها النبي انا احللنا لك ازواجك اللاتي اتيت اجورهن وما ملكت يمينك مما افاء الله عليك وبنات عمك وبنات عماتك وبنات خالك وبنات خالاتك اللاتي هاجرن معك وامراة مومنة ان وهبت نفسها للنبي ان اراد النبي ان يستنكحها خالصة لك من دون المومنين قد علمنا ما فرضنا عليهم في ازواجهم وما ملكت ايمانهم لكيلا يكون عليك حرج وكان الله غفورا رحيما ٥٠

O prophet, We have made lawful for you all your wives whom you have given their dowers, and those (bondwomen) whom you own, out of the captives Allah has given to you as spoils of war, and daughters of your paternal uncle, and daughters of your paternal aunts, and daughters of your maternal uncle, and daughters of your maternal aunts, who have migrated with you, and a believing woman who offers herself for (marrying) the prophet without dower, if the prophet wishes to bring her into his marriage, these rules being exclusive for you, and not for the (rest of the) believers,- We know what We have prescribed for them in respect of their wives and the slave-girls they own - so that there should be no difficulty for you. Allah is Most-Forgiving, Very-Merciful.
