عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ رَآنِي فِي الْمَنَامِ فَقَدْ رَآنِي فَإِنَّ الشَّيْطَانَ لَا يَنْبَغِي لَهُ أَنْ يَتَمَثَّلَ بِمِثْلِي
Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Whoever saw me in a dream, indeed he has seen me, for it is not possible for Satan to assume my form.
