If a Muslim was asleep and in his dream he accepted a belief which is kufr, (e.g. in his dream he accepted the thought that a verse of the Quran is distorted and not correct), will this man remain a Muslim as this thought was accepted when he was asleep or does accepting the thought in sleep still make him a kafir?
He is not accountable for what transpired in his dream. He must not accept what he saw in his dream.
