Al-Muntaqa Ibn al-Jarud 368 — Beginning of the Book of Zakat

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 the region of Khaybar. He came to consult the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! I have obtained such land in Khaybar that I have never acquired wealth better than it. The Prophet (peace and blessings be upon him) said: If you wish, withhold its original (property) and give its produce as charity. So Sayyiduna Umar (may Allah be pleased with him) gave it as charity, stipulating that its original would neither be sold, nor gifted, nor inherited. Its produce was to be given in charity to the poor, the indebted, for the freeing of slaves, in the way of Allah, to travelers, and to guests. There is no harm for the one who manages the land to eat from it in a reasonable manner or to feed a friend, provided he does not accumulate wealth from it.
