حَدَّثَنَا النُّفَيْلِيُّ قَالَ سَمِعْتُ زُهَيْرًا يَقُولُ سَمِعْتُ يَحْيَی بْنَ سَعِيدٍ يَقُولُ سَمِعْتُ أَبَا سَلَمَةَ يَقُولُ سَمِعْتُ أَبَا قَتَادَةَ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الرُّؤْيَا مِنْ اللَّهِ وَالْحُلْمُ مِنْ الشَّيْطَانِ فَإِذَا رَأَی أَحَدُکُمْ شَيْئًا يَکْرَهُهُ فَلْيَنْفُثْ عَنْ يَسَارِهِ ثَلَاثَ مَرَّاتٍ ثُمَّ لِيَتَعَوَّذْ مِنْ شَرِّهَا فَإِنَّهَا لَا تَضُرُّهُ
سنن ابودوٗد · Hadith 5021
Abu Qatadah said: I heard the Messenger of Allah ﷺ 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.
