Sayyiduna Rafi' bin Khadij (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) passed by the land of a man from the Ansar who was cultivating it, and he (peace and blessings be upon him) knew that he was needy. He (peace and blessings be upon him) said: "Whose is this?" He said: It belongs to so-and-so; he has given it to me for rent. The Messenger of Allah (peace and blessings be upon him) said: "If only he had given it to his brother as a gift (without rent)."
