Sayyiduna Abu Qatadah Ansari (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him): "True dreams are from Allah Almighty, and disturbing dreams are from Satan. So when a person sees a disturbing dream that he does not like, he should spit three times to his left and seek refuge with Allah Almighty from the evil of the dream he has seen, then that dream will not harm him."
