Narrator:Abu Qatāda
وعن أبى قتادة رضى الله عنه قال: قال النبي صلى الله عليه وسلم:
"الرؤيا الصالحة -وفى رواية: الرؤيا الحسنة- من الله، والحلم من الشيطان، فمن رأى شيئاً يكره فلينفث عن شماله ثلاثاً، وليتعوذ من الشيطان فإنها لا تضره"
Abu Qatadah (May Allah be pleased with him) reported:
The Prophet (ﷺ) said, "A good vision (dream) is from Allah and a bad dream is from the Satan. He who sees something in a dream that he dislikes, should blow thrice on his left, must seek Allah's Refuge from the evil of the Satan (i.e., by saying: A'udhu billahi minash-Shaitanir-Rajim). Then it will not harm him."
[Al-Bukhari and Muslim].
