يأَيُّهَا النَّبِىُّ إِنَّآ أَحْلَلْنَا لَكَ أَزْوَجَكَ اللاَّتِى ءَاتَيْتَ أُجُورَهُنَّ وَمَا مَلَكَتْ يَمِينُكَ مِمَّآ أَفَآءَ اللَّهُ عَلَيْكَ وَبَنَاتِ عَمِّكَ وَبَنَاتِ عَمَّـتِكَ وَبَنَاتِ خَالِكَ وَبَنَاتِ خَـلَـتِكَ اللاَّتِى هَـجَرْنَ مَعَكَ وَامْرَأَةً مُّؤْمِنَةً إِن وَهَبَتْ نَفْسَهَا لِلنَّبِىِّ إِنْ أَرَادَ النَّبِىُّ أَن يَسْتَنكِحَهَا خَالِصَةً لَّكَ مِن دُونِ الْمُؤْمِنِينَ قَدْ عَلِمْنَا مَا فَرَضْنَا عَلَيْهِمْ فِى أَزْوَجِهِـمْ وَمَا مَلَكَتْ أَيْمَـنُهُمْ لِكَيْلاَ يَكُونَ عَلَيْكَ حَرَجٌ وَكَانَ اللَّهُ غَفُوراً رَّحِيماً
50. O Prophet! Verily, We have made lawful to you your wives, to whom you have paid their due (dowery), and those (slaves) whom your right hand possesses -- whom Allah has given 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 migrated with you, and a believing woman if she offers herself to the Prophet, and the Prophet wishes to marry her -- a privilege for you only, not for the (rest of) the believers. Indeed We know what We have enjoined upon them about their wives and those (slaves) whom their right hands possess, in order that there should be no difficulty on you. And Allah is Ever Oft-Forgiving, Most Merciful. Allah says, addressing His Prophet that He has made lawful for him of women his wives to whom he has given the dowery, which is what is meant by â€their due'', which is used here, as was stated by Mujahid and others. The dowery which he gave to his wives was twelve and half `Uqiyah (measures of gold) so they all received five hundred Dirhams except for Umm Habibah bint Abi Sufyan, to whom An-Najashi, may Allah have mercy on him, gave four hundred Dinars (on behalf of the Prophet ) Safiyyah bint Huyay, whom he chose from among the prisoners of Khaybar, then he set her free, making her release her dowery. A similar case was that of Juwayriyah bint Al-Harith Al-Mustalaqiyyah -- he paid off the contract to buy her freedom from Thabit bin Qays bin Shammas and married her. May Allah be pleased with them all.
