Hazrat Anas (may Allah be pleased with him) was asked about the wages of the one who performs cupping. He said that the Messenger of Allah (peace and blessings be upon him) had cupping done. Abu Taybah (Nafi’ or Maisarah) performed the cupping for him. The Prophet gave him two sa’ of dates as wages, and he spoke to his (Abu Taybah’s) masters (the Banu Harithah), so they reduced the levy they used to take from him. And the Messenger of Allah (peace and blessings be upon him) said:“The best treatment you use is cupping, and the best medicine is the use of Indian aloeswood (oud al-hindi).”

Upon this, it was asked, "O Messenger of Allah! What is the ruling regarding the fat of dead animals? We use it to coat our boats, we use it as oil on hides, and people also use it to light their lamps." The Prophet (peace and blessings be upon him) replied, "No, it is forbidden." On this occasion, the Prophet (peace and blessings be upon him) also said, "May Allah destroy the Jews! When Allah made fat forbidden for them, they melted it, sold it, and consumed its price."
