The Islamic Ruling on Visions

Question:
He says: If a person sees a vision in his dream and does not know whether it is a good vision, or a dream, or a warning about something, what is the Islamic ruling?

Answer:
If he sees a good vision that brings him joy, he should rejoice in it, for it is from Allah (Glorified and Exalted is He), and it is an immediate glad tidings, or it is among the things with which the believer is given glad tidings; it is among the glad tidings, as came in the hadith. As for if the vision is one he dislikes and contains something undesirable, he should leave it, not speak about it, and not interpret it; he should leave it, and it will not harm him. The Prophet (peace and blessings be upon him) guided the one who sees something he dislikes to change the side on which he is lying to the other side, and to say, “I seek refuge in Allah from the evil of what I saw,” and to seek refuge in Allah from the accursed Shaytan. It will not harm him, by the permission of Allah, and he should not interpret it either. Yes.
