مَنْ رَآنِي فِي الْمَنَامِ، فَقَدْ رَآنِي؛ فَإِنَّ الشَّيْطَانَ لَا يَتَمَثَّلُ فِي صُورَتِي
Translation: Whoever sees me in a dream has truly seen me, for Satan cannot assume my form.
Source: البخاري ومسلم
رَآنِي means “he saw me”; the ending نِي means “me.” فَقَدْ رَآنِي emphatically states the consequence. فَإِنَّ introduces the reason, while لَا يَتَمَثَّلُ means “does not assume the form.”
The report teaches that Satan cannot appear in the Prophet’s ﷺ form. It does not mean that every unclear dream becomes a definitive religious ruling or binding evidence for others.
