"In the end of time, the dreams of a believer will hardly ever fail to come true, and the most truthful of them in dreams will be the truest in speech among them. And dreams are three types: The good dreams wihich is glad tidings from Allah, dreams about something that has happened to the man himself, and dreams in which the Shaitan frightens someone. So when one of you sees what he dislikes, then he should get up and perform Salat." Abu Hurairah said: "I like fetters and dislikes, the iron collar. And fetters refers to being firm in the religion." He said: "The Prophet (s. a. w) said: 'Dreams are a portion among the forty_six portions of Prophethood."
