Chapter 50: The Daughter Of One's Brother Through Breast-feeding Is Forbidden For Marriage - كتاب النكاح
أَخْبَرَنِي إِبْرَاهِيمُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ جَابِرِ بْنِ زَيْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ ذُكِرَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم بِنْتُ حَمْزَةَ فَقَالَ " إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ " . قَالَ شُعْبَةُ هَذَا سَمِعَهُ قَتَادَةُ مِنْ جَابِرِ بْنِ زَيْدٍ .
It was narrated that Ibn 'Abbas said:
"Mention was made to the Messenger of Allah of the daughter of Hamzah (as a potential wife). He said: 'She is the daughter of my brother through breast-feeding.'" (One of the narrators) Shu'bah said: "Qatadah heard this from Jabir bin Zaid."
