A few days ago, I saw Prophet Muhammad (peace be upon him) in a dream commanding me to do something. I have read that Satan can’t come in the appearance of prophet Muhammad (peace be upon him) and that the one who sees him in a dream actually sees him. What about receiving commands from Prophet Muhammad (peace be upon him) in a dream?
In Islamic jurisprudence, we have five legal rulings: obligatory (wâjib), preferred (mustahabb), permissible (mubâh), disliked (makrûh), and forbidden (harâm).
Dreams are not and cannot be a source for these rulings. This is the consensus of Ahl al-Sunnah wal Jamâ’ah on the matter.
Anyone who declares that something is preferred or obligatory on the basis of a dream is coming with an innovation in our religion and calling people to fiction and misguidance.
The great jurist, Imam al-Nawawî writes: “If it was the 29th night of Sha`bân and people could not see the crescent, then someone saw the Prophet (peace be upon him) in his dream informing him that ‘tonight is the beginning of Ramadân’, no one would be allowed to fast on the basis of that dream, not the one who saw the dream nor anyone else.” [al-Majmû` (6/292)]
