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 practise mukhabarah (crop-sharing), taking a share of the grain that remains in the channels after harvesting. Then the Messenger of Allah (peace and blessings be upon him) said: "Whoever has land, let him put it to cultivation or let his brother cultivate it; otherwise, let him leave it as it is."
