Abu Qatada ibn Rab'i · The Book of Dreams

"I saw dreams (which perturbed me) but I did not cover myself with a mantle."

A good vision is from Allah and a bad dream (hulm) is from the satan; so if one of you sees anything (in a dream) which he dislikes, he should spit on his left side thrice and seek refuge with Allah from its evil, and then it will never harm him. Abu Salama said: I used to see dreams weighing more heavily upon me than a mountain; but since I heard this hadith I don't care for it (its burden).

The good vision are from Allah and the evil dreams are from the satan. If one sees a dream which one does not like, one should spit on one's left side and seek the refuge of Allah from the satan; it will not do one any harm, and one should not disclose it to anyone and if one sees a good vision one should feel pleased but should not disclose it to anyone but whom one loves.

He who saw me in dream in fact saw the truth (what is true).
