It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a slave of Banu Bayadah performed cupping for the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) gave him one and a half mudd of wheat as wages. If this wage had been unlawful, the Prophet (peace and blessings be upon him) would never have given it to him. And he spoke to his masters regarding this matter, so they reduced some of the amount from him.
