It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) had cupping done, and when the cupper finished, the Prophet (peace and blessings be upon him) said to him: "How much is your wage?" He said: "Two sa’." Then the Prophet (peace and blessings be upon him) bargained with him for a reduction of one sa’ and ordered me to pay him, so I gave him one sa’.
