Nafi reports that Safiyyah bint Abi Ubaid narrated that Umm al-Mu'minin Sayyida Hafsa (may Allah be pleased with her) sent Asim bin Abdullah bin Sa'd, when he was an infant, to her sister Sayyida Fatimah bint Umar bin Khattab (may Allah be pleased with her) so that she could breastfeed him ten times, so that when he grew up, he could appear before her. Sayyida Fatimah (may Allah be pleased with her) breastfed Asim, and when Asim grew up, Sayyida Hafsa (may Allah be pleased with her) used to appear before him.
