It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade treatment through incantations (mantras). In another chain of narration, there is this addition: My maternal uncle used to treat scorpion stings with incantations. When the Prophet (peace and blessings be upon him) prohibited incantations and blowing (over someone), the family of Amr bin Hazm came to the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah! You have forbidden incantations, and I treat scorpion stings with incantations?" And he presented it before the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said, "There is no harm in it. Whoever can benefit his brother should do so."
