Musnad Abu Ya'la al-Mawsili 1:35

Abu Bakr ibn Abi Shaybah narrated to us, Muhammad ibn Fudayl narrated to us, from al-Walid ibn Jumay', from Abu al-Tufayl, who said: Fatimah sent to Abu Bakr and said, "What is the matter with you, O Caliph of the Messenger of Allah, may Allah bless him and grant him peace? Did you inherit the Messenger of Allah, or did his family?" He said, "No, rather his family." She said, "Then what is the matter with the share of the Messenger of Allah, may Allah bless him and grant him peace?" He said, "I heard him say: 'Indeed, when Allah feeds a prophet a provision, then takes him unto Himself, He makes it for the one who comes after him.' So I saw that I should return it to the Muslims." She said, "You and what you heard from the Messenger of Allah."
