Sahih Muslim Book 26, Hadith Number 5450.

Chapter : The excellence of curing (with the help of incantation) the influence of the evil eye and small pustules and the poison (especially of snake and scorpion).

Umm Salama, the wife of Allah’s Apostle (may peace be upon him), reported that Allah’s Messenger (may peace be upon him) said to a small girl in the house of Umm Salama that he had been seeing on her face black stains and told her that that was due to the influence of an evil eye, and he asked that she should be cured with the help of incantation (hoping) that her face should become spotless.
