I used to see a dream which would make me sick till I heard Abu Qatada saying, "I too, used to see a dream which would make me sick till I heard the Prophet ﷺ saying, "A good dream is from Allah, so if anyone of you saw a dream which he liked, he should not tell it to anybody except to the one whom he loves, and if he saw a dream which he disliked, then he should seek refuge with Allah from its evil and from the evil of Satan, and spit three times (on his left) and should not tell it to anybody, for it will not harm him. "  

سَمِعْتُ أَبَا سَلَمَةَ يَقُولُ لَقَدْ كُنْتُ أَرَى الرُّؤْيَا فَتُمْرِضُنِي حَتَّى سَمِعْتُ أَبَا قَتَادَةَ يَقُولُ وَأَنَا كُنْتُ لأَرَى الرُّؤْيَا تُمْرِضُنِي حَتَّى سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الرُّؤْيَا الْحَسَنَةُ مِنَ اللَّهِ فَإِذَا رَأَى أَحَدُكُمْ مَا يُحِبُّ فَلاَ يُحَدِّثْ بِهِ إِلاَّ مَنْ يُحِبُّ وَإِذَا رَأَى مَا يَكْرَهُ فَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا وَمِنْ شَرِّ الشَّيْطَانِ وَلْيَتْفِلْ ثَلاَثًا وَلاَ يُحَدِّثْ بِهَا أَحَدًا فَإِنَّهَا لَنْ تَضُرَّهُ  

I used to see (such horrible dreams) that I fell ill. I saw Abu Qatada who also said: I used to see dreams which made me sick until I heard Messenger of Allah ﷺ as saying: Good dreams are from Allah, so if any one of you sees which he likes he should not disclose it to one but whom he loves, but if he sees something which he does not like he should spit on his left side thrice and seek refuge with Allah from the mischief of the Satan and its mischief (i.e. of the dream), and he should not relate it to anyone, then it would not harm him.  

وَأَنَا كُنْتُ لأَرَى الرُّؤْيَا فَتُمْرِضُنِي حَتَّى سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ فَإِذَا رَأَى أَحَدُكُمْ مَا يُحِبُّ فَلاَ يُحَدِّثُ بِهَا إِلاَّ مَنْ يُحِبُّ وَإِنْ رَأَى مَا يَكْرَهُ فَلْيَتْفِلْ عَنْ يَسَارِهِ ثَلاَثًا وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّ الشَّيْطَانِ وَشَرِّهَا وَلاَ يُحَدِّثْ بِهَا أَحَدًا فَإِنَّهَا لَنْ تَضُرَّهُ  

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  

I used to see (such horrible dreams) that I fell ill. I saw Abu Qatada who also said: I used to see dreams which made me sick until I heard Messenger of Allah ﷺ as saying: Good dreams are from Allah, so if any one of you sees which he likes he should not disclose it to one but whom he loves, but if he sees something which he does not like he should spit on his left side thrice and seek refuge with Allah from the mischief of the Satan and its mischief (i.e. of the dream), and he should not relate it to anyone, then it would not harm him. (Using translation from Muslim 2261g)  

وَأَنَا إِنْ كُنْتُ لَأَرَى الرُّؤْيَا تُمْرِضُنِي حَتَّى سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ فَإِذَا رَأَى أَحَدُكُمْ مَا يُحِبُّ فَلْيَحْمَدِ اللَّهَ وَلَا يُحَدِّثْ بِهَا إِلَّا مَنْ يُحِبُّ وَإِذَا رَأَى مَا يَكْرَهُه فَلْيَتْفُلْ عَنْ يَسَارِهِ ثَلَاثًا وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا وَلَا يُحَدِّثْ بِهَا أَحَدًا فَإِنَّهَا لَنْ تَضُرَّهُ»  

[Machine] I heard Abu Qatadah saying, "I used to see dreams that would make me sick until I heard the Prophet ﷺ saying, 'Good dreams are from Allah, so if any one of you sees a dream that he likes, he should narrate it to the one whom he loves. And if he sees a dream that he dislikes, he should seek refuge with Allah from its evil and should not mention it to anyone, for it will not harm him.'"  

سَمِعْتُ أَبَا قَتَادَةَ يَقُولُ كُنْتُ أَرَى الرُّؤْيَا فَتُمْرِضُنِي حَتَّى سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ «الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ فَإِذَا رَأَى أَحَدُكُمْ مَا يُحِبُّ فَلْيَقُصَّهُ عَلَى مَنْ يُحِبُّ وَإِذَا رَأَى أَحَدُكُمْ مَا يَكْرَهُ فَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا وَلْيَتْفُلْ عَنْ يَسَارِهِ ثَلَاثًا»  

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). (Using translation from Muslim 2261d)   

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمُ الشَّيْءَ يَكْرَهُهُ فَلْيَنْفُثْ عَنْ يَسَارِهِ ثَلَاثَ مَرَّاتٍ إِذَا اسْتَيْقَظَ وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا فَإِنَّهَا لَنْ تَضُرَّهُ إِنْ شَاءَ اللَّهُ» قَالَ أَبُو سَلَمَةَ «إِنْ كُنْتُ لَأَرَى الرُّؤْيَا هِيَ أَثْقَلُ عَلَيَّ مِنَ الْجَبَلِ فَلَمَّا سَمِعْتُ هَذَا الْحَدِيثَ مَا كُنْتُ أُبَالِيهَا»  

"الرُّؤيَا الصَّالحِةُ مِنَ الله ﷻ فَإِذَا رَأى أَحَدُكُمْ مَا يُحِبُّ فَلَا يُحَدِّثْ بهَا إلا مَنْ يُحِبُّ، وَإِذَا رأى مَا يَكْرَهُ فَليتْفُل عَنْ يَسَاره ثَلاثًا، وَلْيَتَعَوَّذ باللهِ مِن شَرِّ الشَّيطَان الرَّجيم، وشرِّها، ولا يُحَدِّثْ بها أَحدًا، فإِنها لا تَضُرُّه".
