Sayyiduna Rafi’ bin Khadij (may Allah be pleased with him) narrates: Previously, we used to lease out land, and the owner of the land would exclude a specific part of the field and the area around the water source. Sometimes, the produce of one part would be ruined while the other part would remain fine, so the Prophet Muhammad (peace and blessings be upon him) forbade this. Sayyiduna Rafi’ (may Allah be pleased with him) says: However, if the land is leased in exchange for a specified thing, then there is no harm in it.
