I said: Do you not fear Allah ? Did you not hear the Messenger of Allah (ﷺ) say: We are not inherited. Whatever we leave is sadaqah (alms). This property belongs to the family of Muhammad for their emergent needs and their guest. When I die, it will go to him who becomes ruler after me.
Sunan Abi Dawud Book 20, Hadith 50
← Previous Hadith When the Messenger of Allah (ﷺ) died, the wives of the Prophet (ﷺ) intended to send 'Uthman b. 'Affan to Abu Bakr to ask him their cost of living from (the inheritance of) the Prophet (ﷺ). Thereupon 'Aishah said: Did not the Messenger of Allah (ﷺ) say: We are not inherited. Whatever we leave is sadaqah.

Sunan Abi Dawud Book 20, Hadith 49 Next Hadith → That he and 'Uthman b. 'Affan went to the Messenger of Allah (ﷺ) talking to him about the fifth which he divided among the Banu Hisham and Abu 'Abd al-Muttalib. I said: Messenger of Allah, you have divided (the fifth) among our brethren Banu 'Abd al-Muttalib, but you have not given us anything, though our relationship to you is the same as theirs. The Prophet (ﷺ) said: The Banu Hisham and the Banu 'Abd al-Muttalib are one. Jubair said: He did not divide the fifth among the Banu 'Abd Shams and the Banu Nawfal as he divided among the Banu Hashim and the Banu 'Abd al-Muttalib. He said: Abu Bakr used to divide the fifth like the division of Messenger of Allah (ﷺ) except that he did not give the relatives of the Messenger of Allah (ﷺ), as he gave them. 'Umar b. al-Khattab and 'Uthman after him used to give them (a portion) from it.
