Sahih Bukhari Volume 7, Book 67, Hadith 5109

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ عُرْوَةَ بْنَ الزُّبَيْرِ، أَخْبَرَهُ أَنَّ زَيْنَبَ ابْنَةَ أَبِي سَلَمَةَ أَخْبَرَتْهُ أَنَّ أُمَّ حَبِيبَةَ قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ انْكِحْ أُخْتِي بِنْتَ أَبِي سُفْيَانَ‏.‏ قَالَ ‏"‏ وَتُحِبِّينَ ‏"‏‏.‏ قُلْتُ نَعَمْ، لَسْتُ بِمُخْلِيَةٍ، وَأَحَبُّ مَنْ شَارَكَنِي فِي خَيْرٍ أُخْتِي‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ إِنَّ ذَلِكَ لاَ يَحِلُّ لِي ‏"‏‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ فَوَاللَّهِ إِنَّا لَنَتَحَدَّثُ أَنَّكَ تُرِيدُ أَنْ تَنْكِحَ دُرَّةَ بِنْتَ أَبِي سَلَمَةَ‏.‏ قَالَ ‏"‏ بِنْتَ أُمِّ سَلَمَةَ ‏"‏‏.‏ فَقُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ فَوَاللَّهِ لَوْ لَمْ تَكُنْ فِي حَجْرِي مَا حَلَّتْ لِي إِنَّهَا لاَبْنَةُ أَخِي مِنَ الرَّضَاعَةِ، أَرْضَعَتْنِي وَأَبَا سَلَمَةَ ثُوَيْبَةُ فَلاَ تَعْرِضْنَ عَلَىَّ بَنَاتِكُنَّ وَلاَ أَخَوَاتِكُنَّ ‏"

Narrated By Um Habiba : I said, "O Allah's Apostle! Marry my sister, the daughter of Abu Sufyan." He said, "Do you like that?" I said, "Yes, for even now I am not your only wife; and the most beloved person to share the good with me is my sister." The Prophet said, "But that is not lawful for me (i.e., to be married to two sisters at a time.)" I said, "O Allah's Apostle! By Allah, we have heard that you want to marry Durra, the daughter of Abu Salama." He said, "You mean the daughter of Um Salama?" I said, "Yes." He said, "By Allah ! Even if she were not my stepdaughter, she would not be lawful for me to marry, for she is my foster niece, for Thuwaiba has suckled me and Abu Salama; so you should neither present your daughters, nor your sisters to me."
