Sahih al-Bukhari · Book 91: Interpretation of Dreams · Whoever saw the Prophet (saws) in a dream
Narrated Abu Sa`id Al-Khudri:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، حَدَّثَنَا اللَّيْثُ ، حَدَّثَنِي ابْنُ الْهَادِ ، عَنْ عَبْدِ اللَّهِ بْنِ خَبَّابٍ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ، سَمِعَ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " مَنْ رَآنِي فَقَدْ رَأَى الْحَقَّ، فَإِنَّ الشَّيْطَانَ لاَ يَتَكَوَّنُنِي".
The Prophet (ﷺ) said, "Who ever sees me (in a dream) then he indeed has seen the truth, as Satan cannot appear in my shape."
