The physician, the one who treats and the circumciser

Abd al-Aziz bin Umar said: Those who came to my father related to me that the Prophet (peace and blessings be upon him) said: "Any practitioner who treats a people while he had no knowledge at all of treatment before that, and he worsens the illness, is liable."

Abd al-Aziz said: This liability is not for worsening the illness; rather, it is for cutting veins and lancing.

Abu Qurrah said that Umar bin Abd al-Aziz held the circumciser liable.

Abu al-Malih said that a woman who performed circumcision in Madinah circumcised a girl, and the girl died. Sayyiduna Umar (may Allah be pleased with him) said to her: Could you not have left this much? And he placed the girl's blood money upon the family of the woman who performed the circumcision.
