The first incident that took place immediately after the death of the Messenger of Allah, which the Sunnis as well as the historians recorded, was the argument between Fatimah al-Zahra and Abu Bakr regarding the alleged saying, "We, the prophets, do not leave an inheritance, all that we leave behind should go to charity." Fatimah denied and refuted this saying, with the support of the Book of Allah, and protested against Abu Bakr's allegation and said that her father, the Messenger of Allah, could not contradict the Book of Allah which was revealed to him, for Allah, praise be to Him the Most High, said: “Allah enjoins you concerning your children.
The male shall have the equal of the portion of two females..." (Holy Qur'an 4:11). This Qur'anic verse is general and is applicable to prophets and non-prophets alike. She also protested with the following words of the most High: "And Sulaiman was Dawood's heir" (Holy Qur an 27:16), and both of them were prophets.
Allah, Glory be to Him, also said: "...Grant me from Thyself an heir, who should inherit from me and inherit from the children of Yaqub, and make him, my Lord, one with whom You are well pleased." (Holy Qur'an 19:5-6) The second incident that involved Abu Bakr during the early days of his caliphate, which the Sunni historians recorded, was his disagreement with the nearest of all people to him, Umar ibn al-Khattab.
The incident revolves around Abu Bakr's decision to fight those who refused to pay Zakat (alms) and kill them, but Umar protested and advised him not to fight them because he had heard the Messenger of Allah saying: I have been ordered to fight the people until they say, "There is no other god but Allah and Muhammad is the Messenger of Allah." And he who says it can keep his wealth to himself and I have no right to his (blood), and he is accountable to Allah.
