It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: I, Sayyida Fatima, Sayyiduna Abbas, and Sayyiduna Zaid bin Haritha (may Allah be pleased with them), gathered in the presence of the Messenger of Allah. Sayyiduna Abbas (may Allah be pleased with him) said: O Messenger of Allah! Now I have grown old, my bones have become weak, and I have endured much hardship, so if you deem it appropriate, please order for me a certain amount of grain. The Prophet (peace and blessings be upon him) said: We will do so. Then Sayyiduna Zaid bin Haritha (may Allah be pleased with him) said: O Messenger of Allah! You had given me a piece of land, which was my means of livelihood, but then you took it back; if you deem it appropriate, please give it to me again. The Prophet (peace and blessings be upon him) said: We will do so. Then I said: O Messenger of Allah! If you deem it appropriate, appoint me as the guardian of that right which Allah Almighty has mentioned in His Book in the form of khumus, so that I may distribute it during your lifetime, so that after you no one may dispute with me about it. The Prophet (peace and blessings be upon him) said: We will do so. Thus, the Prophet (peace and blessings be upon him) appointed me as its guardian, and I distributed it during his blessed life. Then Sayyiduna Abu Bakr (may Allah be pleased with him) appointed me as its guardian, and I distributed it during his lifetime as well. Then Sayyiduna Umar (may Allah be pleased with him) appointed me as its guardian, and I distributed it during his lifetime, until it was the last year of Sayyiduna Umar (may Allah be pleased with him) and a great amount of wealth came to him.
