The Prophet ﷺ said, "A good dream that comes true is from Allah, and a bad dream is from Satan, so if anyone of you sees a bad dream, he should seek refuge with Allah from Satan and should spit on the left, for the bad dream will not harm him."  

عَنِ النَّبِيِّ ﷺ قَالَ الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ فَلْيَتَعَوَّذْ مِنْهُ وَلْيَبْصُقْ عَنْ شِمَالِهِ فَإِنَّهَا لاَ تَضُرُّهُ وَعَنْ أَبِيهِ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي قَتَادَةَ عَنْ أَبِيهِ عَنِ النَّبِيِّ ﷺ مِثْلَهُ  

The Prophet ﷺ said, "The (good) dreams of a faithful believer is a part of the forty-six parts of prophetism:'  

عَنِ النَّبِيِّ ﷺ قَالَ رُؤْيَا الْمُؤْمِنِ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ  

Messenger of Allah ﷺ said, "The (good) dream of a faithful believer is a part of the forty-six parts of prophetism."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «رُؤْيَا الْمُؤْمِنِ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ۔»  

I heard Messenger of Allah ﷺ saying, "A good dream is a part of the forty six parts of prophetism."  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا الصَّالِحَةُ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ
