Musnad Abu Ya'la al-Mawsili 109:7

2006. Ishaq narrated to us, Jarir narrated to us, from al-A'mash, from Abu Sufyan, from Jabir, who said: A man used to perform ruqyah (incantations) for the scorpion sting, but the Messenger of Allah (peace and blessings of Allah be upon him) forbade ruqyah. The man said: "O Messenger of Allah, you have forbidden ruqyah, and I used to perform ruqyah for the scorpion sting." The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever among you is able to benefit his brother, let him do so."
