Abayah bin Rifa'ah (may Allah have mercy on him) narrates from his father (Rifa'ah), who said: My father (Sayyiduna Rafi' bin Khadij (may Allah be pleased with him)) died and left land, a slave girl, a slave who did cupping and a water-carrying camel. They came to the Messenger of Allah (peace and blessings be upon him) about this. He (peace and blessings be upon him) said to them about the land: "Cultivate it or give it to someone as a gift", and he forbade them the earnings of the slave girl and said: "Feed the earnings of the cupper to the water-carrying camel."
