'A'isha (the wife of Allah's Apostle) said
When Allah's Messenger (ﷺ) fell ill, Gabriel used to recite this: "In the name of Allah, may He cure you from all kinds of illnesses and safeguard you from the evil of a jealous one when he feels jealous and from the evil influence of eye."
Abu Sa'id reported that Gabriel came to Allah's Messenger (ﷺ) and said
Muhammad, have you fallen ill? Thereupon he said: Yes. He (Gabriel) said: "In the name of Allah I exorcise you from everything and safeguard you from every evil that may harm you and from the eye of a jealous one. Allah would cure you and I invoke the name of Allah for you."
Abu Huraira reported so many abidith from Allah's Messenger (ﷺ) and he reported Allah's Messenger (ﷺ) as saying
The influence of an evil eye is a fact.
Ibn 'Abbas reported Allah's Messenger (ﷺ) as saying
The influence of an evil eye is a fact; if anything would precede the destiny it would be the influence of an evil eye, and when you are asked to take bath (as a cure) from the influence of an evil eye, you should take bath.
