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