Sunan Abi Dawud 2968

Narrated 'Aishah, wife of Prophet (ﷺ):Fatimah daughter of Messenger of Allah (ﷺ) sent a messenger to Abu Bakr demanding from him in inheritance of the Messenger of Allah (ﷺ) from what Allah bestowed on him at Medina and Fadak, and what remained of the fifth of Khaibar. Abu Bakr said: The Messenger of Allah (ﷺ) has said: We are not inherited. Whatever we leave is sadaqah. The family of Muhammad will eat from this property. I swear by Allah I shall not change it from the former condition of its being sadaqah as it was in the time of the Messenger of Allah (ﷺ). I shall deal with it as the Messenger of Allah dealt with it. Abu Bakr, therefore, refused to give anything to Fatimah from it
