Sahih al-Bukhari 5106
Narrated Um Habiba:
I said, "O Allah's Messenger (ﷺ)! Do you like to have (my sister) the daughter of Abu Sufyan?" The Prophet (ﷺ) 
said, "What shall I do (with her)?" I said, "Marry her." He said, "Do you like that?" I said, "(Yes), for 
even now I am not your only wife, so I like that my sister should share you with me." He said, "She is 
not lawful for me (to marry)." I said, "We have heard that you want to marry." He said, "The daughter 
of Um Salama?" I said, "Yes." He said, "Even if she were not my stepdaughter, she should be 
unlawful for me to marry, for Thuwaiba suckled me and her father (Abu Salama). So you should 
neither present your daughters, nor your sisters, to me."
حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ، عَنْ أُمِّ حَبِيبَةَ، قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ هَلْ لَكَ فِي بِنْتِ أَبِي سُفْيَانَ قَالَ ‏"‏ فَأَفْعَلُ مَاذَا ‏"‏‏.‏ قُلْتُ تَنْكِحُ‏.‏ قَالَ ‏"‏ أَتُحِبِّينَ ‏"‏‏.‏ قُلْتُ لَسْتُ لَكَ بِمُخْلِيَةٍ، وَأَحَبُّ مَنْ شَرِكَنِي فِيكَ أُخْتِي‏.‏ قَالَ ‏"‏ إِنَّهَا لاَ تَحِلُّ لِي ‏"‏‏.‏ قُلْتُ بَلَغَنِي أَنَّكَ تَخْطُبُ‏.‏ قَالَ ‏"‏ ابْنَةَ أُمِّ سَلَمَةَ ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ لَوْ لَمْ تَكُنْ رَبِيبَتِي مَا حَلَّتْ لِي، أَرْضَعَتْنِي وَأَبَاهَا ثُوَيْبَةُ، فَلاَ تَعْرِضْنَ عَلَىَّ بَنَاتِكُنَّ وَلاَ أَخَوَاتِكُنَّ ‏"‏‏.‏ وَقَالَ اللَّيْثُ حَدَّثَنَا هِشَامٌ دُرَّةُ بِنْتُ أَبِي سَلَمَةَ‏.‏
