Thabit bin Aslam Albanani ثابت بن أسلم البناني · Chapters On Dreams

"Dreams are from Allah and Hulum are from Shaitan. So when one of you sees something that bothers him, then let him spit on his left three times, and let him seek refuge in Allah from its evil. Then it will not harm him."

"When the Messenger of Allah (s.a.w) had led us in Subh(Fajr prayer), he turned to face the people and said: 'Did any of you have a dream during the night?'" This is how Bundar reported this Hadith, with its brevity, from Wahib bin Jarir.
