Um Habiba said to Messenger of Allah ﷺ "We have heard that you want to marry Durra bint Abu-Salama." Messenger of Allah ﷺ said, "Can she be married along with Um Salama (her mother)? Even if I have not married Um Salama, she would not be lawful for me to marry, for her father is my foster brother." (Using translation from Bukhārī 5123)
لِرَسُولِ اللهِ ﷺ إِنَّا قَدْ تَحَدَّثْنَا أَنَّكَ نَاكِحٌ دُرَّةَ بِنْتَ أَبِي سَلَمَةَ فَقَالَ رَسُولُ اللهِ ﷺ «أَعَلَى أُمِّ سَلَمَةَ لَوْ أَنِّي لَمْ أَنْكِحْ أُمَّ سَلَمَةَ مَا حَلَّتْ لِي إِنَّ أَبَاهَا أَخِي مِنَ الرَّضَاعَةِ»
