Sahih Muslim , Book 29, Hadith 5636 (USC-MSA) ⓘ
Abu Huraira reported: I heard Allah's Messenger as saying: He who saw me in a dream would soon see me in the state of wakefulness, or as if he saw me in a state of wakefulness, for the satan does not appear in my form.
وَحَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ، شِهَابٍ حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ رَآنِي فِي الْمَنَامِ فَسَيَرَانِي فِي الْيَقَظَةِ أَوْ لَكَأَنَّمَا رَآنِي فِي الْيَقَظَةِ لاَ يَتَمَثَّلُ الشَّيْطَانُ بِي " .
