Belief in the evil eye is found in the Islamic doctrine, based upon the statement of Prophet Muhammad, "The influence of an evil eye is a fact.." [Sahih Muslim, Book 26, Number 5427] [REF].
Among those who do not take the evil eye literally, either by reason of the culture in which they were raised or because they simply do not believe it, the phrase, "to give someone the evil eye" usually means simply to glare at the person in anger or disgust.
