Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that Sayyiduna Umar (may Allah be pleased with him) acquired a piece of land in Khaybar. He went to the Prophet Muhammad (peace and blessings be upon him) and said, "I have obtained a piece of land such that I have never acquired a better one than this before. What do you command me regarding it?" The Prophet Muhammad (peace and blessings be upon him) said: "If you wish, keep the land and give its produce as charity." The narrator says: So Sayyiduna Umar (may Allah be pleased with him) gave its produce as charity, in such a way that the land could neither be sold, nor gifted, nor inherited. (Its produce) would be given to the poor, relatives, slaves, those striving in the way of Allah, and travelers. Whoever is its caretaker will not be sinful if he eats from it in a reasonable manner, or feeds a friend from it, but the condition is that he does not accumulate wealth from it.
