باب فَضَائِلِ فَاطِمَةَ بِنْتِ النَّبِيِّ عَلَيْهَا الصَّلاَةُ وَالسَّلاَمُ ‏‏
Sahih Muslim 2449 a

Miswar b. Makhramali reported that he heard Allah's Messenger (ﷺ) say, as he sat on the pulpit:

The sons of Hisham b. Mughira have asked my permission to marry their daughter with 'Ali b. Abi Talib (that refers to the daughter of Abu Jahl for whom 'All had sent a proposal for marriage). But I would not allow them, I would not allow them, I would not allow them (and the only alternative possible is) that 'Ali should divorce my daughter (and then marry their daughter), for my daughter is part of me. He who disturbs her in fact disturbs me and he who offends her offends me.
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، كِلاَهُمَا عَنِ اللَّيْثِ بْنِ سَعْدٍ، قَالَ ابْنُ يُونُسَ حَدَّثَنَا لَيْثٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُبَيْدِ اللَّهِ بْنِ أَبِي مُلَيْكَةَ الْقُرَشِيُّ التَّيْمِيُّ، أَنَّحَدَّثَهُ أَنَّهُ، سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى الْمِنْبَرِ وَهُوَ يَقُولُ ‏ "‏ إِنَّ بَنِي هِشَامِ بْنِ الْمُغِيرَةِ اسْتَأْذَنُونِي أَنْ يُنْكِحُوا ابْنَتَهُمْ عَلِيَّ بْنَ أَبِي طَالِبٍ فَلاَ آذَنُ لَهُمْ ثُمَّ لاَ آذَنُ لَهُمْ ثُمَّ لاَ آذَنُ لَهُمْ إِلاَّ أَنْ يُحِبَّ ابْنُ أَبِي طَالِبٍ أَنْ يُطَلِّقَ ابْنَتِي وَيَنْكِحَ ابْنَتَهُمْ فَإِنَّمَا ابْنَتِي بَضْعَةٌ مِنِّي يَرِيبُنِي مَا رَابَهَا وَيُؤْذِينِي مَا آذَاهَا ‏"‏ ‏.‏
