I heard the Prophet ﷺ saying, "A good dream is from Allah, and a bad dream is from Satan. So if anyone of you sees (in a dream) something he dislikes, when he gets up he should blow thrice (on his left side) and seek refuge with Allah from its evil for then it will not harm him."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمْ شَيْئًا يَكْرَهُهُ فَلْيَنْفِثْ حِينَ يَسْتَيْقِظُ ثَلاَثَ مَرَّاتٍ وَيَتَعَوَّذْ مِنْ شَرِّهَا فَإِنَّهَا لاَ تَضُرُّهُ وَقَالَ أَبُو سَلَمَةَ وَإِنْ كُنْتُ لأَرَى الرُّؤْيَا أَثْقَلَ عَلَىَّ مِنَ الْجَبَلِ فَمَا هُوَ إِلاَّ أَنْ سَمِعْتُ هَذَا الْحَدِيثَ فَمَا أُبَالِيهَا  

A good vision is from Allah and a bad dream (hulm) is from the satan; so if one of you sees anything (in a dream) which he dislikes, he should spit on his left side thrice and seek refuge with Allah from its evil, and then it will never harm him. Abu Salama said: I used to see dreams weighing more heavily upon me than a mountain; but since I heard this hadith I don't care for it (its burden).  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمْ شَيْئًا يَكْرَهُهُ فَلْيَنْفِثْ عَنْ يَسَارِهِ ثَلاَثَ مَرَّاتٍ وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا فَإِنَّهَا لَنْ تَضُرَّهُ فَقَالَ إِنْ كُنْتُ لأَرَى الرُّؤْيَا أَثْقَلَ عَلَىَّ مِنْ جَبَلٍ فَمَا هُوَ إِلاَّ أَنْ سَمِعْتُ بِهَذَا الْحَدِيثِ فَمَا أُبَالِيهَا  

I heard the Messenger of Allah (May peace be upon him) say: A good vision comes from Allah and a dream (hulm) from the devil, so when one of you sees what he dislikes, he must spit on his left (three times), and seek refuge in Allah from its evil. It will then not harm him.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمْ شَيْئًا يَكْرَهُهُ فَلْيَنْفُثْ عَنْ يَسَارِهِ ثَلاَثَ مَرَّاتٍ ثُمَّ لْيَتَعَوَّذْ مِنْ شَرِّهَا فَإِنَّهَا لاَ تَضُرُّهُ  

Yahya related to me from Malik from Yahya ibn Said that Abu Salama ibn Abd ar-Rahman said, "I heard Abu Qatada ibn Ribiyy say that he heard the Messenger of Allah ﷺ say, 'The good dream is from Allah, and the bad dream is from shaytan. When you see what you dislike, spit to your left side three times when you wake up, and seek refuge with Allah from its evil. It will not harm you then, Allah willing.' " Abu Salama said, "I would see dreams which weighed on me more heavily than a mountain. When I heard this hadith, I was not concerned about it."  

يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمُ الشَّىْءَ يَكْرَهُهُ فَلْيَنْفُثْ عَنْ يَسَارِهِ ثَلاَثَ مَرَّاتٍ إِذَا اسْتَيْقَظَ وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا فَإِنَّهَا لَنْ تَضُرَّهُ إِنْ شَاءَ اللَّهُ قَالَ أَبُو سَلَمَةَ إِنْ كُنْتُ لأَرَى الرُّؤْيَا هِيَ أَثْقَلُ عَلَىَّ مِنَ الْجَبَلِ فَلَمَّا سَمِعْتُ هَذَا الْحَدِيثَ فَمَا كُنْتُ أُبَالِيهَا
