حَدَّثَنَا أَبُو الرَّبِيعِ، سُلَيْمَانُ بْنُ دَاوُدَ الْعَتَكِيُّ حَدَّثَنَا حَمَّادٌ، - يَعْنِي ابْنَ زَيْدٍ - حَدَّثَنَا أَيُّوبُ، وَهِشَامٌ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنْ رَآنِي فِي الْمَنَامِ فَقَدْ رَآنِي فَإِنَّ الشَّيْطَانَ لاَ يَتَمَثَّلُ بِي ‏"‏ ‏.‏

Jabir reported Allah's Messenger (ﷺ) as saying

He who saw me in sleep in fact saw me, for it is not possible for the satan to appear in my form; and he also said: When any one of you sees a hulm he should not inform anyone, for it is a sort of vain sport of devil in the state of sleep.
