Messenger of Allah, I have seen in the state of sleep as if my head had been cut off. Thereupon Allah's Apostle ﷺ laughed and said: When the satan plays with any one of you in the state of sleep, do not mention it to the people; and in the hadith transmitted by Abu Bakr (the words are): "If one of you is played with, and he did not make any mention of the word: "Satan."
جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ رَأَيْتُ فِي الْمَنَامِ كَأَنَّ رَأْسِي قُطِعَ قَالَ فَضَحِكَ النَّبِيُّ ﷺ وَقَالَ إِذَا لَعِبَ الشَّيْطَانُ بِأَحَدِكُمْ فِي مَنَامِهِ فَلاَ يُحَدِّثْ بِهِ النَّاسَ وَفِي رِوَايَةِ أَبِي بَكْرٍ إِذَا لُعِبَ بِأَحَدِكُمْ وَلَمْ يَذْكُرِ الشَّيْطَانَ
