Mua'wiya bin Hisham al-Qsar معاوية بن هشام القصار · Interpretation of Dreams

“The Messenger of Allah (ﷺ) drew aside the curtain when he was sick, and the rows (of worshippers) were behind Abu Bakr. He said: ‘O people, nothing of the glad tidings of prophecy is left except a good dream that a Muslim sees or is seen about him.’”

“(Good) dreams come from Allah and (bad) dreams come from Satan, so if anyone of you sees something that he dislikes, let him spit dryly to his left three times, and seek refuge with Allah from the accursed Satan three times, and turn over onto his other side.”
