It is narrated from Abdur Rahman bin Abu Laila, who says: I heard Amir al-Mu’minin Sayyiduna Ali (may Allah be pleased with him) say: I, Sayyida Fatima, Sayyiduna Abbas, and Sayyiduna Zaid bin Haritha gathered in the presence of the Messenger of Allah (peace and blessings be upon him). Sayyiduna Abbas said: O Messenger of Allah! I have grown old, my bones have become weak, and my burdens and hardships have increased, so if you deem it appropriate, please order for me such and such amount of grain. The Prophet (peace and blessings be upon him) said: We will do so. Then Sayyida Fatima (may Allah be pleased with her) said: O Messenger of Allah! Just as you have ordered for your uncle, if you deem it appropriate, please order for me as well. The Prophet (peace and blessings be upon him) said: We will do so as well. Then Sayyiduna Zaid bin Haritha (may Allah be pleased with him) said: O Messenger of Allah! You had given me a piece of land, my livelihood depended on it, but then you took it back from me. If you deem it appropriate, please return that land to me. The Prophet (peace and blessings be upon him) said: Yes, we will do so. Then I (Ali) said: O Messenger of Allah! If you deem it appropriate, appoint me as the guardian of that right which Allah Almighty has granted us in His Book in the form of khums, so that I may distribute it during your lifetime, and so that no one may snatch this right from us after you. The Prophet (peace and blessings be upon him) said: We will do so. Thus, the Messenger of Allah (peace and blessings be upon him) made me responsible for it, and I continued to distribute it during his blessed life. Then Sayyiduna Abu Bakr (may Allah be pleased with him) kept that right entrusted to me, and I continued to distribute it during his caliphate. Then Sayyiduna Umar (may Allah be pleased with him) also appointed me as its guardian, and I continued to distribute it during his caliphate, until the last year of his caliphate began, at which time a great amount of wealth came to him.
