Narrated Ibn `Abbas: It was said to the Prophet, "Won't you marry the daughter of Hamza?" He said, "She is my foster niece (brother's daughter). "
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ جَابِرِ بْنِ زَيْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قِيلَ لِلنَّبِيِّ صلى الله عليه وسلم أَلاَ تَزَوَّجُ ابْنَةَ حَمْزَةَ قَالَ " إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ " . وَقَالَ بِشْرُ بْنُ عُمَرَ حَدَّثَنَا شُعْبَةُ سَمِعْتُ قَتَادَةَ سَمِعْتُ جَابِرَ بْنَ زَيْدٍ مِثْلَهُ.
