Sunnan Abu Dawud Collection: ::Book Number 19:: Hadith # 2963
Narrated Aisha, Ummul Mu'minin: Fatimah was demanding (the property of) sadaqah of the Apostle of Allah (peace_be_upon_him) at Medina and Fadak, and what remained from the fifth of Khaybar. Aisha quoted AbuBakr as saying: The Apostle of Allah (peace_be_upon_him) said: We are not inherited; whatever we leave is sadaqah. The family of Muhammad will eat from this property, that is, from the property of Allah. They will not take more then their sustenance.
