Sayyidah Aishah (may Allah be pleased with her) narrated that Sayyidah Fatimah (may Allah be pleased with her), the daughter of the Messenger of Allah (peace and blessings be upon him), asked Sayyiduna Abu Bakr (may Allah be pleased with him), after the death of the Messenger of Allah (peace and blessings be upon him), to divide for her her inheritance from what the Messenger of Allah (peace and blessings be upon him) left of what Allah had restored to him. Sayyiduna Abu Bakr (may Allah be pleased with him) said to her: The Messenger of Allah (peace and blessings be upon him) said: "We are not inherited from; whatever we leave is charity." Sayyidah Fatimah (may Allah be pleased with her) became angry and left Sayyiduna Abu Bakr (may Allah be pleased with him), and she remained like that until she died; she lived for six months after the death of the Messenger of Allah (peace and blessings be upon him). Sayyidah Fatimah (may Allah be pleased with her) had asked Sayyiduna Abu Bakr (may Allah be pleased with him) for her share of what the Messenger of Allah (peace and blessings be upon him) left: from Khaybar, Fadak and his charity in Madinah. Sayyiduna Abu Bakr (may Allah be pleased with him) refused her that and said: "I will not leave anything that the Messenger of Allah (peace and blessings be upon him) used to do except that I do it too; I fear that if I leave anything of his practice, I will deviate." As for his charity in Madinah, Sayyiduna Umar (may Allah be pleased with him) handed it over to Sayyiduna Ali and Sayyiduna Abbas (may Allah be pleased with them both), and Sayyiduna Ali (may Allah be pleased with him) prevailed over it. As for Fadak and Khaybar, Sayyiduna Umar (may Allah be pleased with him) kept hold of them and said: "They are the charity of the Messenger of Allah (peace and blessings be upon him); they were for the obligations that befell him and his emergencies, and their matter rests with whoever is in authority." They have remained so until today.
