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." – Sound Chain

أَخْبَرَنَا أَبُو الْمُغِيرَةِ حَدَّثَنَا الْأَوْزَاعِيُّ عَنْ يَحْيَى عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ عَنْ أَبِيهِ قَالَ

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» – إسناده صحيح
