It is narrated from Sayyiduna Rafi' bin Khadij (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) passed by some crops and said: "Whose crop is this?" The people said: It belongs to so-and-so, and the land belongs to so-and-so. So he (peace and blessings be upon him) forbade that and said: "Whoever has land, let him cultivate it himself or give it to his brother."
