Abayah bin Rifa’ah bin Rafi’ bin Khadij says: When my grandfather passed away, leaving behind a slave woman, a camel, a slave, a barber, and some land, the Messenger of Allah (peace and blessings be upon him) forbade the earnings from the slave woman. Imam Shu’bah says: It was forbidden due to the risk of immorality. And the Prophet (peace and blessings be upon him) further said:“Make the barber’s earnings fodder for the camels.”And regarding the land, he said:“Cultivate it yourself or leave it as it is.”

Haram bin Sa'd bin Muhaisah narrates that Muhaisah asked the Messenger of Allah (peace and blessings be upon him) about the earnings of his barbers. The Prophet (peace and blessings be upon him) forbade him from it. He kept asking the same question repeatedly, until the Prophet (peace and blessings be upon him) said: "(Then do this:) feed their earnings to your camels or give it to your slaves to eat."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Three (things) are forbidden: the earnings of the cupper, the earnings of a prostitute woman, and the price of a dog, except for a hunting dog."

It is narrated from Sayyiduna Rafi‘ bin Khadij (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "The price of a dog is impure, the earnings of a prostitute are impure, and the earnings of a cupper are impure."
