'Urwah narrated that Zainab bint Abi Salamah -whose mother was Umm Salamah, the wife of the Prophet- told him that Umm Habibah bint Abi Sufyan told her that she said:"O Messenger of Allah, marry my sister, the daughter of Abu Sufyan." She said: "The Messenger of Allah said: 'Would you like that?' I said: 'Yes; I do not have you all to myself and I would like to share this goodness with my sister.' The Prophet said: 'Your sister is not permissible for me (to marry).' I said: 'By Allah, O Messenger of Allah, we have been saying that you want to marry Durrah bint Abi Salamah.' He said: 'The daughter of Umm Salamah?' I said: 'Yes.' He said: 'By Allah, even if she were not my stepdaughter who is in my care, she would not be permissible for me (to marry), because she is the daughter of my brother through breast-feeding. Thuwaibah breastfed Abu Salamah and I. So do not offer your daughters or sisters to me in marriage.'"
أَخْبَرَنَا عِمْرَانُ بْنُ بَكَّارٍ، قَالَ حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَنْبَأَنَا شُعَيْبٌ، قَالَ أَخْبَرَنِي الزُّهْرِيُّ، قَالَ أَخْبَرَنِي عُرْوَةُ، أَنَّ زَيْنَبَ بِنْتَ أَبِي سَلَمَةَ، - وَأُمُّهَا أُمُّ سَلَمَةَ زَوْجُ النَّبِيِّ صلى الله عليه وسلم - أَخْبَرَتْهُ أَنَّ أُمَّ حَبِيبَةَ بِنْتَ أَبِي سُفْيَانَ أَخْبَرَتْهَا أَنَّهَا قَالَتْ يَا رَسُولَ اللَّهِ أَنْكِحْ أُخْتِي بِنْتَ أَبِي سُفْيَانَ . قَالَتْ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَوَتُحِبِّينَ ذَلِكِ " . فَقُلْتُ نَعَمْ لَسْتُ لَكَ بِمُخْلِيَةٍ وَأَحَبُّ مَنْ يُشَارِكُنِي فِي خَيْرٍ أُخْتِي . فَقَالَ النَّبِيُّ صلى الله عليه وسلم " إِنَّ أُخْتَكِ لاَ تَحِلُّ لِي " . فَقُلْتُ وَاللَّهِ يَا رَسُولَ اللَّهِ إِنَّا لَنَتَحَدَّثُ أَنَّكَ تُرِيدُ أَنْ تَنْكِحَ دُرَّةَ بِنْتَ أَبِي سَلَمَةَ . فَقَالَ " بِنْتُ أُمِّ سَلَمَةَ " . فَقُلْتُ نَعَمْ . فَقَالَ " وَاللَّهِ لَوْلاَ أَنَّهَا رَبِيبَتِي فِي حَجْرِي مَا حَلَّتْ لِي إِنَّهَا لاَبْنَةُ أَخِي مِنَ الرَّضَاعَةِ أَرْضَعَتْنِي وَأَبَا سَلَمَةَ ثُوَيْبَةُ فَلاَ تَعْرِضْنَ عَلَىَّ بَنَاتِكُنَّ وَلاَ أَخَوَاتِكُنَّ " .
