(33) باب عَرْضِ الإِنْسَانِ ابْنَتَهُ أَوْ أُخْتَهُ عَلَى أَهْلِ الْخَيْرِ
Narrated Zainab bint Salama:
Um Habiba said to Allah's Messenger (ﷺ) "We have heard that you want to marry Durra bint Abu-Salama." Allah's Messenger (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."
