Abu Saʿid al-Khudri (ra) said, “I heard the Prophet (saw) say, ‘If anyone of you has a dream he likes, then it is from Allah, and he should thank Allah for it and transmit it to others; but if he has a different dream, i.e., a dream that he dislikes, then it is from Satan, and he should seek refuge with Allah from its evil, and he should not mention it to anybody, for it will not harm him.’” (al-Bukhari, al-Taʿbir, 3)
