He who saw me in a dream in fact saw me, for the satan does not appear in my form.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ رَآنِي فِي الْمَنَامِ فَقَدْ رَآنِي فَإِنَّ الشَّيْطَانَ لاَ يَتَمَثَّلُ بِي  

I heard Messenger of Allah ﷺ 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.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ رَآنِي فِي الْمَنَامِ فَسَيَرَانِي فِي الْيَقَظَةِ أَوْ لَكَأَنَّمَا رَآنِي فِي الْيَقَظَةِ لاَ يَتَمَثَّلُ الشَّيْطَانُ بِي  

He who saw me in dream in fact saw the truth (what is true).  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ رَآنِي فَقَدْ رَأَى الْحَقَّ  

The above two hadith have been narrated likewise through another chain of transmitters.  

حَدَّثَنَا عَمِّي فَذَكَرَ الْحَدِيثَيْنِ جَمِيعًا بِإِسْنَادَيْهِمَا سَوَاءً مِثْلَ حَدِيثِ يُونُسَ  

He who saw me in sleep in fact saw me, for it is not possible for the satan to appear in my form; and he also said: When any one of you sees a hulm he should not inform anyone, for it is a sort of vain sport of devil in the state of sleep.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ رَآنِي فِي النَّوْمِ فَقَدْ رَآنِي إِنَّهُ لاَ يَنْبَغِي لِلشَّيْطَانِ أَنْ يَتَمَثَّلَ فِي صُورَتِي وَقَالَ إِذَا حَلَمَ أَحَدُكُمْ فَلاَ يُخْبِرْ أَحَدًا بِتَلَعُّبِ الشَّيْطَانِ بِهِ فِي الْمَنَامِ  

He who saw me in a dream in fact saw me, for the satan cannot assume my form.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ رَآنِي فِي النَّوْمِ فَقَدْ رَآنِي فَإِنَّهُ لاَ يَنْبَغِي لِلشَّيْطَانِ أَنْ يَتَشَبَّهَ بِي
