O Prophet, indeed We have made lawful to you your wives to whom you have given their due compensation and those your right hand possesses from what Allāh has returned to you [of captives] 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 believing woman if she gives herself to the Prophet [and] if the Prophet wishes to marry her; [this is] only for you, excluding the [other] believers. We certainly know what We have made obligatory upon them concerning their wives and those their right hands possess, [but this is for you] in order that there will be upon you no discomfort [i.e., difficulty]. And ever is Allāh Forgiving and Merciful.

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.
