(a companion of the Prophet ﷺ and one of his cavalry men) "I heard Messenger of Allah ﷺ saying, "A good dream is from Allah, and a bad dream is from Satan; so, if anyone of you had a bad dream which he disliked, then he should spit on his left and seek refuge with Allah from it, for it will not harm him."  

قَتَادَةَ الأَنْصَارِيّ َ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ وَفُرْسَانِهِ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ أَحَدُكُمُ الْحُلُمَ يَكْرَهُهُ فَلْيَبْصُقْ عَنْ يَسَارِهِ وَلْيَسْتَعِذْ بِاللَّهِ مِنْهُ فَلَنْ يَضُرَّهُ  

I used to see dreams (and was so much perturbed) that I began to quiver and have temperature, but did not cover myself with a mantle. I met Abu Qatada and made a mention of that to him. He said: I heard Messenger of Allah ﷺ as saying: A good vision comes from Allah and a (bad) dream (hulm) from devil. So when one of you sees a bad dream (hulm) which he does not like, he should spit on his left side thrice and seek refuge with Allah from its evil; then it will not harm him.  

كُنْتُ أَرَى الرُّؤْيَا أُعْرَى مِنْهَا غَيْرَ أَنِّي لاَ أُزَمَّلُ حَتَّى لَقِيتُ أَبَا قَتَادَةَ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ أَحَدُكُمْ حُلْمًا يَكْرَهُهُ فَلْيَنْفُثْ عَنْ يَسَارِهِ ثَلاَثًا وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّهَا فَإِنَّهَا لَنْ تَضُرَّهُ  

I used to see dreams (and was so much perturbed) that I began to quiver and have temperature, but did not cover myself with a mantle. I met Abu Qatada and made a mention of that to him. He said: I heard Messenger of Allah ﷺ as saying: A good vision comes from Allah and a (bad) dream (hulm) from devil. So when one of you sees a bad dream (hulm) which he does not like, he should spit on his left side thrice and seek refuge with Allah from its evil; then it will not harm him. (Using translation from Muslim 2261a)   

كُنْتُ أَلْقَى مِنَ الرُّؤْيَا شِدَّةً غَيْرَ أَنِّي لَا أُزَمَّلُ حَتَّى حَدَّثَنِي أَبُو قَتَادَةَ أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ أَحَدُكُمْ حُلْمًا يَكْرَهُهُ فَلْيَبْصُقْ عَنْ يَسَارِهِ ثَلَاثَ بَصَقَاتٍ وَلْيَسْتَعِذْ بِاللهِ مِنَ الشَّيْطَانِ فَإِنَّهُ لَا يَضُرُّهُ  

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. (Using translation from Abū Dāʾūd 5021)   

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ الرُّؤْيَا مِنَ اللهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا رَأَى أَحَدُكُمْ شَيْئًا يَكْرَهُهُ فَلْيَبْصُقْ عَنْ شِمَالِهِ ثَلَاثَ مَرَّاتٍ وَلْيَسْتَعِذْ بِاللهِ مِنْ شَرِّهَا فَإِنَّهَا لَنْ تَضُرَّهُ  

[Machine] The Messenger of Allah ﷺ said, "A good dream is from Allah, and a bad dream is from Satan. So if anyone of you sees a dream that he dislikes, let him spit to his left three times and seek refuge in Allah from Satan, for it will not harm him."  

قَالَ رَسُولُ اللَّهِ ﷺ «الرُّؤْيَا الصَّالِحَةُ مِنَ اللَّهِ وَالْحُلْمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ أَحَدُكُمْ حُلْمًا يَخَافُهُ فَلْيَبْصُقْ عَنْ شِمَالِهِ ثَلَاثَ مَرَّاتٍ وَلْيَتَعَوَّذْ بِاللَّهِ مِنَ الشَّيْطَانِ فَإِنَّهَا لَا تَضُرُّهُ»

(Using translation from Bukhārī 7005)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «الرُّؤْيَا الصَّالِحَةُ مِنَ اللهِ وَالْحُلُمُ مِنَ الشَّيْطَانِ فَإِذَا حَلَمَ أَحَدُكُمُ الْحُلُمَ يَكْرَهُهُ فَلْيَبْصُقْ عَنْ يَسَارِهِ ثَلَاثًا وَلْيَسْتَعِذْ بِاللهِ مِنْهُ فَلَنْ يَضُرَّهُ»
