O Prophet! Indeed, We [We] have made lawful to you your wives (to) whom you have given their bridal money and whom you possess rightfully from those (whom) has given Allah to you, and (the) daughters (of) your paternal uncles and (the) daughters (of) your paternal aunts and (the) daughters (of) your maternal uncles and (the) daughters (of) your maternal aunts who emigrated with you, and a woman believing if she gives herself to the Prophet if wishes the Prophet to marry her - only for you, from excluding the believers.
