Chapter 33, Verse 51

O Prophet, We have made lawful to thee thy wives whom thou hast paid their dowries, and those whom thy right hand possesses from among those whom Allah has given thee as gains of war, and the daughters of thy paternal uncle, and the daughters of thy paternal aunts, and the daughters of thy maternal uncle, and the daughters of thy maternal aunts who have emigrated with thee, and any other believing woman if she offers herself for marriage to the Prophet provided the Prophet desires to marry her; this is only for thee, as against other believers — We have already made known what We have enjoined on them concerning their wives and those whom their right hands possess — in order that there may be no difficulty for thee in the discharge of thy work. And Allah is Most Forgiving, Merciful.
