Sayyiduna Jabir (may Allah be pleased with him) said: In the time of the Messenger of Allah (peace and blessings be upon him) we used to take land along the banks of the streams for a third or a quarter. The Messenger of Allah (peace and blessings be upon him) stood up and said: "Whoever has land should cultivate it; if he cannot do so himself, let him give it to his brother; and if he does not take it either, let him just leave it as it is."
