Hazrat Dimaad bin Tha’labah Azdi (radhiyallahu ‘anhu) was a close friend of Rasulullah (sallallahu ‘alaihi wasallam) from the pre-Islamic era of ignorance. He would recite different invocations and blow on people as a form of treatment.

When he came to Makkah Mukarramah after Rasulullah (sallallahu ‘alaihi wasallam) was bestowed with prophethood, he saw a group of boys following Rasulullah (sallallahu ‘alaihi wasallam). Some were calling him a sorcerer and fortune teller while others called him insane and a madman. Hazrat Dimaad (radhiyallahu ‘anhu) appeared before Rasulullah (sallallahu ‘alaihi wasallam) and said, “I know how to treat insanity. Give me permission to treat you, and perhaps Allah Ta‘ala will cure you at my hands.”
