Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that Abu Hind cupped the Prophet (peace and blessings be upon him) on the crown of his head because of a pain he had, and he (peace and blessings be upon him) said: "If there is cure in anything with which you treat yourselves, it is cupping."
