حَدَّثَنَا عَفَّانُ حَدَّثَنَا هَمَّامٌ حَدَّثَنَا قَتَادَةُ عَنْ جَابِرِ بْنِ زَيْدٍ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أُرِيدَ عَلَى بِنْتِ حَمْزَةَ فَقَالَ إِنَّهَا ابْنَةُ أَخِي مِنْ الرَّضَاعَةِ وَإِنَّهَا لَا تَحِلُّ لِي وَيَحْرُمُ مِنْ الرَّضَاعَةِ مَا يَحْرُمُ مِنْ الرَّحِمِ
مسند امام احمد بن حنبل · Hadith 3044
It was narrated from Ibn 'Abbas (RA) that the daughter of Hamzah was suggested (as a potential wife) to the Prophet (PBUH) and he said: "She is the daughter of my brother through breast- feeding and she is not permissible for me. What becomes mahram (forbidden for marriage) through breastfeeding is that which becomes mahram through blood ties”.
