It is narrated from Hazrat Abu Ramtha. He says that I was young and accompanied my father to the service of the Holy Prophet (peace and blessings be upon him). Abu Ramtha says: My father said to the Holy Prophet (peace and blessings be upon him), "I am a physician, so please show me the raised flesh on your back." The Holy Prophet (peace and blessings be upon him) asked, "What will you do with it?" My father replied, "I will cut it off." The Holy Prophet (peace and blessings be upon him) said, "You are not a physician, rather you are a friend. Its physician is the One who made it." Or he said, "The One who created it."
