Malik related to me from Ibn Shihab from Urwa ibn az-Zubayr fromA'isha, umm al-muminin that when the Messenger of Allah, may Allahbless him and grant him peace, died, the wives of the Prophet, mayAllah bless him and grant him peace, wanted to send Uthman ibn Affanto Abu Bakr as-Siddiq to ask him about their inheritance from theMessenger of Allah, may Allah bless him and grant him peace A'ishasaid to them, "Didn't the Messenger of Allah, may Allah bless him andgrant him peace, say, 'No one inherits from us. What we leave issadaqa.' "
