Narrated Imran ibn Husayn: The Prophet ﷺ said: No spell is to be used except for the evil eye or a scorpion sting.

Narrated Sahl ibn Hunayf: I passed by a river. I entered it and took a bath in it. When I came out, I had fever. The Messenger of Allah ﷺ was informed about it. He said: Ask Abu Thabit to seek refuge in Allah from that I asked: O my Lord, will the spell be useful? He replied: No, the spell is to be used except for the evil eye or a snake bite or a scorpion sting. Abu Dawud said: Humah means the biting of snakes and sting of the poisonous insects.

Anas reported the Prophet ﷺ as saying: No spell is to be used except for the evil eye, or sting of poisonous insects, or bleeding. The narrator al-‘Abhas did mention the words “evil eye”. The is the version of Sulaiman bin Dawud.
