Sahih al-Bukhari 6114

'Urwa related from 'A'isha: Fatima and al-'Abbas went to Abu Bakr to ask for their inheritance from the Messenger of Alla, may Allah bless him and grant him peace. They were asking for their land at Fadak and their share of Khaybar. Abu Bakr said to them, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'We do not leave inheritance. What we leave is sadaqa, but the family of Muhammad may eat from this property.'" Abu Bakr said, 'By Allah, I will not leave anything that I saw the Messenger of Allah, may Allah bless him and grant him peace, doing. Rather I will do it." Therefore Fatima shunned him and did not speak to him until she died. 'Urwa related from 'A'isha that the Prophet, may Allah bless him and grant him peace, said, "We do not leave inheritance. What we leave is sadaqa."
