"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.'" (Using translation from Nasāʾī 3284)  

أَنَّ زَيْنَبَ بِنْتَ أَبِي سَلَمَةَ وَأُمُّهَا أُمُّ سَلَمَةَ زَوْجُ النَّبِيِّ ﷺ أَخْبَرَتْهُ أَنَّ أُمَّ حَبِيبَةَ بِنْتَ أَبِي سُفْيَانَ أَخْبَرَتْهَا أَنَّهَا قَالَتْ يَا رَسُولَ اللهِ أَنْكِحْ أُخْتِي ابْنَةَ أَبِي سُفْيَانَ قَالَتْ فَقَالَ لِي رَسُولُ اللهِ ﷺ «أَوَ تُحِبِّينَ ذَلِكَ؟» فَقَالَتْ نَعَمْ لَسْتُ بِمُخْلِيَةٍ وَأَحَبُّ مَنْ شَارَكَنِي فِي خَيْرٍ أُخْتِي فَقَالَ النَّبِيُّ ﷺ «إِنَّ ذَلِكَ لَا يَحِلُّ لِي» فَقُلْتُ وَاللهِ يَا رَسُولَ اللهِ إِنَّا لَنَتَحَدَّثُ أَنَّكَ تُرِيدُ أَنْ تَنْكِحَ دُرَّةَ بِنْتَ أَبِي سَلَمَةَ فَقَالَ «ابْنَةُ أُمِّ سَلَمَةَ؟» فَقُلْتُ نَعَمْ فَقَالَ «وَاللهِ لَوْ أَنَّهَا لَمْ تَكُنْ رَبِيبَتِي فِي حَجْرِي مَا حَلَّتْ لِي إِنَّهَا لَابْنَةُ أَخِي مِنَ الرَّضَاعَةِ أَرْضَعْتِنِي وَأَبَاهَا ثُوَيْبَةُ فَلَا تَعْرِضْنَ عَلَيَّ بَنَاتِكُنَّ وَلَا أَخَوَاتِكُنَّ» أَدْخَلَ هِشَامُ بْنُ عُرْوَةَ بَيْنَ زَيْنَبَ وَبَيْنَ أُمِّ حَبِيبَةَ أُمَّ سَلَمَةَ  

"O Messenger of Allah, what do you think of my sister?" He said: "What for?" She said: "For marriage." He said: "Would you like that?" She said: "Yes; I do not have you all to myself, and I would like to share this goodness with my sister." He said: "She is not permissible for me (to marry)." She said: "But I heard that you want to marry Durrah, the daughter of Umm Salamah." He said: "The daughter of Umm Salamah?" She said: "Yes." He said: "By Allah, even if she were not my stepdaughter she would not be permissible for me (to marry), because she is the daughter of my brother through breast-feeding. Do not offer your daughters and sisters to me in marriage." (Using translation from Nasāʾī 3287)  

أَنَّهَا قَالَتْ يَا رَسُولَ اللهِ هَلْ لَكَ فِي أُخْتِي؟ قَالَ «فَأَصْنَعُ مَاذَا؟» قَالَتْ تَزَوَّجْهَا قَالَ «فَإِنَّ ذَلِكَ أَحَبُّ إِلَيْكِ؟» قَالَتْ نَعَمْ لَسْتُ لَكَ بِمُخْلِيَةٍ وَأَحَبُّ مَنْ يَشْرَكُنِي فِي خَيْرٍ أُخْتِي قَالَ «فَإِنَّهَا لَا تَحِلُّ لِي» قَالَتْ فَإِنَّهُ قَدْ بَلَغَنِي أَنَّكَ تُخْطَبُ دُرَّةَ بِنْتَ أُبِي سَلَمَةَ قَالَ «ابْنَةُ أُمِّ سَلَمَةَ؟» قَالَتْ نَعَمْ قَالَ وَاللهِ لَوْ لَمْ تَكُنْ رَبِيبَتِي مَا حَلَّتْ لِي إِنَّهَا لَابْنَةُ أَخِي مِنَ الرَّضَاعَةِ قَالَ فَلَا تَعْرِضْنَ عَلَيَّ بَنَاتِكُنَّ وَلَا أَخَوَاتِكُنَّ
