It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once some people came to the service of the Prophet (peace and blessings be upon him) and said, "One of our companions is suffering from an illness. Can we treat him by cauterization?" The Prophet (peace and blessings be upon him) remained silent for a while without giving any answer, and after some time said, "If you wish, cauterize him, and if you wish, heat a stone and apply it."
