Jabir told that a man came to the Prophet (ﷺ) and said:

“In a dream I seemed to see any head had been cut off." The Prophet (ﷺ) laughed and replied: “When the devil makes sport of any of you in a dream he should not tell people about it." Muslim transmitted it.

وَعَن جَابر قَالَ: جَاءَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: رَأَيْتُ فِي الْمَنَامِ كَأَنَّ رَأْسِي قُطِعَ قَالَ: فَضَحِكَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَالَ: «إِذَا لَعِبَ الشَّيْطَانُ بِأَحَدِكُمْ فِي مَنَامِهِ فَلَا يُحَدِّثْ بِهِ النَّاس» . رَوَاهُ مُسلم
