Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Rimthah (may Allah be pleased with him) says that I went to the Prophet Muhammad (peace and blessings be upon him) with my father. My father said to him: "This thing (i.e., the Seal of Prophethood) that is on your back, show it to me, I am a physician (I treat such things)." The Prophet (peace and blessings be upon him) said: "Allah is the Physician, you are only a kind man. Its Physician is the One who created it."
