[Machine] The Prophet ﷺ was asked to marry the daughter of Hamzah, but he replied, "She is not permissible for me because she is the daughter of my foster brother. Allah has prohibited what is prohibited in terms of blood relations." In another narration, he said, "She is not appropriate for me because she is the daughter of my foster brother. What is prohibited in terms of blood relations is also prohibited in terms of breastfeeding."  

النَّبِيَّ ﷺ أُرِيدَ عَلَى ابْنَةِ حَمْزَةَ فَقَالَ إِنَّهَا لَا تَحِلُّ لِي إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ وَإِنَّ اللهَ حَرَّمَ مِنَ الرَّضَاعَةِ مَا حَرَّمَ مِنَ النَّسَبِ وَفِي رِوَايَةِ هُدْبَةَ إِنَّهَا لَا تَصْلُحُ لِي إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ وَيَحْرُمُ مِنَ الرَّضَاعَةِ مَا يَحْرُمُ مِنَ النَّسَبِ
