حَدَّثَنَا عَبْدُ اللهِ بْنُ عَبْدِ الرَّحْمَنِ الدَّارِمِيُّ، قَالَ: حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، قَالَ: حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ الْمُخْتَارِ، قَالَ: حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسٍ
أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: مَنْ رَآنِي فِي الْمَنَامِ فَقَدْ رَآنِي، فَإِنَّ الشَّيْطَانَ لا يَتَخَيَّلُ بِي وَقَالَ: وَرُؤْيَا الْمُؤْمِنِ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ
“The Prophet (sallallahu alayhi wa sallam) said (sallallahu alayhi wa sallam): ‘If someone sees me in his sleep, he has indeed seen me, for Satan cannot impersonate me!’ He also said: ‘The vision of the believer is one of forty-six parts of Prophethood.’”
