´Rafi' bin Khadij narrated that the Messenger of Allah said to Rafi':` "Do you rent out your arable land?" I said: "Yes, O Messenger of Allah. We rent it out in return for one-quarter, and in return for (a number of) Wasqs of barley." The Messenger of Allah said: "Do not do that. Cultivate it (yourselves), or lend it, or keep it."
