Abu Sa'id Al-Khudri RA reported: I heard the Prophet (peace be upon him) saying, "When one of you sees a dream that he likes, then it is from Allah. He should praise Allah for it and relate it to (others)." [Bukhari & Muslim] Commentary: There are clear instructions from our Prophet about both good and bad dreams. A good dream means a good news sent by Allah to a person who has seen it. It should be related only to those who are close to his heart and not to such people who may start nourishing malice against him like the brothers of Prophet Yusuf (Joseph). A bad dream should be attributed to Satan and not be described to others because it often causes one to be pessimistic and it may be taken as a bad omen, which is not allowed in Islam. Rather, a man should seek Allah's Refuge against its evil. And if he puts faith in Allah, no harm will come to him.
