"I said: 'O Messenger of Allah, why do you choose wives from among Quraish and not from among us?' He said: 'Do you have anyone in mind?' I said: 'Yes, the daughter of Hamzah.' The Messenger of Allah said: 'She is not permissible for me (to marry); she is the daughter of my brother through breast-feeding.'"  

قُلْتُ يَا رَسُولَ اللَّهِ مَا لَكَ تَنَوَّقُ فِي قُرَيْشٍ وَتَدَعُنَا قَالَ وَعِنْدَكَ أَحَدٌ قُلْتُ نَعَمْ بِنْتُ حَمْزَةَ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّهَا لاَ تَحِلُّ لِي إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ  

"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."  

ذُكِرَ لِرَسُولِ اللَّهِ ﷺ بِنْتُ حَمْزَةَ فَقَالَ إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ قَالَ شُعْبَةُ هَذَا سَمِعَهُ قَتَادَةُ مِنْ جَابِرِ بْنِ زَيْدٍ  

"She is the daughter of my brother through breast-feeding, and what becomes unlawful (for marriage) through breast-feeding is the same as that which becomes unlawful through lineage."  

أَنَّ رَسُولَ اللَّهِ ﷺ أُرِيدَ عَلَى بِنْتِ حَمْزَةَ فَقَالَ إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ وَإِنَّهُ يَحْرُمُ مِنَ الرَّضَاعِ مَا يَحْرُمُ مِنَ النَّسَبِ
