It is narrated from Jabir (may Allah be pleased with him) that Umm Salamah (may Allah be pleased with her) sought permission from the Prophet (peace and blessings be upon him) for cupping, so the Prophet (peace and blessings be upon him) ordered Abu Taybah to cup her. Jabir (may Allah be pleased with him) said: I think Abu Taybah was either her foster brother or a boy who had not yet reached puberty.
