Narrated `Aisha:
Fatima 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 task 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. When Fatima was alive, the people used to respect `Ali much, but after her death, `Ali noticed a change in the people's attitude towards him. So `Ali sought reconciliation with Abu Bakr and gave him an oath of allegiance. `Ali had not given the oath of allegiance during those months (i.e. the period between the Prophet's death and Fatima's death). `Ali sent someone to Abu Bakr saying, "Come to us, but let nobody come with you," as he disliked that `Umar should come, `Umar said (to Abu Bakr), "No, by Allah, you shall not enter upon them alone " Abu Bakr said, "What do you think they will do to me? By Allah, I will go to them' So Abu Bakr entered upon them, and then `Ali uttered Tashah-hud and said (to Abu Bakr), "We know well your superiority and what Allah has given you, and we are not jealous of the good what Allah has bestowed upon you, but you did not consult us in the question of the rule and we thought that we have got a right in it because of our near relationship to Allah's Messenger (s.a.w.a.) ." Thereupon Abu Bakr's eyes flowed with tears. And when Abu Bakr spoke, he said, "By Him in Whose Hand my soul is to keep good relations with the relatives of Allah's Messenger (s.a.w.a.) is dearer to me than to keep good relations with my own relatives. But as for the trouble which arose between me and you about his property, I will do my best to spend it according to what is good, and will not leave any rule or regulation which I saw Allah's Messenger (s.a.w.a.) following, in disposing of it, but I will follow." On that `Ali said to Abu Bakr, "I promise to give you the oath of allegiance in this after noon." So when Abu Bakr had offered the Zuhr prayer, he ascended the pulpit and uttered the Tashah-hud and then mentioned the story of `Ali and his failure to give the oath of allegiance, and excused him, accepting what excuses he had offered; Then `Ali (got up) and praying (to Allah) for forgiveness, he uttered Tashah-hud, praised Abu Bakr's right, and said, that he had not done what he had done because of jealousy of Abu Bakr or as a protest of that Allah had favored him with. `Ali added, "But we used to consider that we too had some right in this affair (of rulership) and that he (i.e. Abu Bakr) did not consult us in this matter, and therefore caused us to feel sorry." On that all the Muslims became happy and said, "You have done the right thing." The Muslims then became friendly with `Ali as he returned to what the people had done (i.e. giving the oath of allegiance to Abu Bakr)
It is narrated on the authority of Urwa b. Zubair who narrated from A'isha that she informed him that Fatima, 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 (to be given in) 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 (may peace be upun him) 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, buried her at night. He did not inform Abu Bakr about her death and offered the funeral prayer over her himself. During the lifetime of Fatima, 'All received (special) regard from the people. After she had died, he felt estrangement in the faces of the people towards him. So he sought to make peace with Abu Bakr and offer his allegiance to him. He had not yet owed allegiance to him as Caliph during these months. He sent a person to Abu Bakr requesting him to visit him unaccompanied by anyone (disapproving the presence of Umar). 'Umar said to Abu Bakr: BY Allah, you will not visit them alone. Abu Bakr said: What will they do to me? By Allah, I will visit them. And he did pay them a visit alone. 'All recited Tashahhud (as it is done in the beginning of a religious sermon) ; then said: We recognise your moral excellence and what Allah has bestowed upon you. We do not envy the favour (i. e. the Catiphate) which Allah nas conferred upon you; but you have done it (assumed the position of Caliph) alone (without consulting us), and we thought we had a right (to be consulted) on account of our kinship with the Messenger of Allah (s.a.w.a.). He continued to talk to Abu Bakr (in this vein) until the latter's eyes welled up with tears. Then Abd Bakr spoke and said: By Allah, in Whose Hand is my life, the kinship of the Messenger of Allah (s.a.w.a.) is dearer to me than the kinship of my own people. As regards the dispute that has arisen between you and me about these properties, I have not deviated from the right course and I have not given up doing about them what the Messenger of Allah (s.a.w.a.) used to do. So 'Ali said to Abu Bakr: This aftetnoon is (fixed) for (swearing) allegiance (to you). So when Abu Bakr had finished his Zuhr prayer, he ascended the pulpit and recited Tashahhud, and described the status of 'Ali, his delay in swearing allegiance and the excuse which lie had offered to him (for this delay). (After this) he asked for God's forgiveness. Then 'Ali b. Abu Talib recited the Tashahhud. extolled the merits of Abu Bakr and (said that) his action was nott prompted by any jealousy of Abu Bakr on his part or his refusal to accept the high position which Allah had conferred upon him, (adding: ) But we were of the opinion that we should have a share in the government, but the matter had been decided without taking us into confidence, and this displeased us. (Hence the delay in offering allegiance. The Muslims were pleased with this (explanation) and they said: You have done the right thing. The Muslims were (again) favourably inclined to 'Ali since he adopted the proper course of action.
