Sayyiduna Abu Qatadah reports: I heard the Prophet Muhammad (peace be upon him) say: "Dreams are from Allah Almighty, and bad dreams are from Satan. So when anyone sees something he dislikes, when he wakes up, he should spit three times to his left and seek refuge in Allah from the evil of that dream. If Allah wills, that dream will not harm him." The narrator named Abu Salamah reports: Sometimes I used to see such dreams that were heavier for me than a mountain, but when I heard this hadith, I no longer cared about them.
