Hazrat Abu Hurairah narrates that the Messenger of Allah, peace and blessings be upon him, entered upon me while I was suffering. Then he said: Shall I not blow upon you with a ruqyah with the blowing that Jibreel taught me? With the name of Allah, I blow upon you, and may Allah grant you shifa from every organ that afflicts you, and from the evil of the blowers on knots, and from the evil of the envier when he envies.
