Narrated `Aisha: Fatima (sa) the daughter of the Prophet (s.a.w.a.) sent someone to Abu Bakr (when he was a caliph), asking for her inheritance of what Allah's Messenger (s.a.w.a.) had left of the property bestowed on him by Allah from the Fai (i.e. booty gained without fighting) in Medina, and Fadak, and what remained of the Khumus of the Khaibar booty. On that, Abu Bakr said, "Allah's Messenger (s.a.w.a.) said, "Our property is not inherited. Whatever we leave, is Sadaqa, but the family of (the Prophet) Muhammad can eat of this property.' By Allah, I will not make any change in the state of the Sadaqa of Allah's Messenger (s.a.w.a.) and will leave it as it was during the lifetime of Allah's Messenger (s.a.w.a.), and will dispose of it as Allah's Messenger (s.a.w.a.) used to do." So Abu Bakr refused to give anything of that to Fatima. So she became angry with Abu Bakr and kept away from him, and did not talk to him till she died. She remained alive for six months after the death of the Prophet. When she died, her husband `Ali, buried her at night without informing Abu Bakr and he said the funeral prayer by himself.

It is narrated on the authority of Urwa b. Zubair who narrated from A'isha that she informed him that Fatima (sa), daughter of the Messenger of Allah (s.a.w.a.), sent someone to Abu Bakr to demand from him her share of the legacy left by the Messenger of Allah (s.a.w.a.) from what Allah had bestowed upon him at Medina and Fadak and what was left from one-filth of the income (annually received) from Khaibar. Abu Bakr said:

The Messenger of Allah (s.a.w.a.) said:" We (prophets) do not have any heirs; what we leave behind is charity." The household of the Messenger of Allah (s.a.w.a.) will live on the income from these properties, but, by Allah, I will not change the charity of the Messenger of Allah (s.a.w.a.) from the condition in which it was in his own time. I will do the same with it as the Messenger of Allah (s.a.w.a.) himself used to do. So Abu Bakr refused to hand over anything from it to Fatima who got angry with Abu Bakr for this reason. She forsook him and did not talk to him until the end of her life. She lived for six months after the death of the Messenger of Allah (s.a.w.a.). When she died, her husband. 'Ali b. Abu Talib (as), buried her at night. He did not inform Abu Bakr about her death and offered the funeral prayer over her himself.
