ʿAbdullāh b. Al-Zubayr said, “I have never seen two women more generous than ‘Ā'ishah and Asmā'. They had different ways of being generous. As for ‘Ā'ishah, she used to gather things, until she had a collection, then she would distribute it. As for Asmā', she would never keep anything until the next day.”
