حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ عَلِيِّ بْنِ زَيْدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ
قَالَ: قَالَ عَلِيٌّ قُلْتُ: يَا رَسُولَ اللَّهِ أَلَا أَدُلُّكَ عَلَى أَجْمَلِ فَتَاةٍ فِي قُرَيْشٍ قَالَ وَمَنْ هِيَ قُلْتُ ابْنَةُ حَمْزَةَ قَالَ: أَمَا عَلِمْتَ أَنَّهَا ابْنَةُ أَخِي مِنْ الرَّضَاعَةِ إِنَّ اللَّهَ حَرَّمَ مِنْ الرَّضَاعَةِ مَا حَرَّمَ مِنْ النَّسَبِ
Ali (رضي الله عنه) said: I said: O Messenger of Allah (sallallahu alayhi wa sallam), shall I not tell you about the most beautiful girl of Quraish? He said: “who is she?” I said: The daughter of Hamzah. He said: ‘Don’t you know that she is the daughter of my brother through breastfeeding? Allah has forbidden (for marriage) through breastfeeding that which He has forbidden through blood ties.’
