عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَمْ يَبْقَ مِنَ النُّبُوَّةِ إِلَّا الْمُبَشِّرَاتُ» قَالُوا: وَمَا الْمُبَشِّرَاتُ؟ قَالَ: «الرُّؤْيَا الصالحةُ» . رَوَاهُ البُخَارِيّ وَزَادَ مَالِكٌ بِرِوَايَةِ عَطَاءِ بْنِ يَسَارٍ: «يَرَاهَا الرجل الْمُسلم أَو ترى لَهُ»

Jabir reported God’s messenger as saying

"When one of you sees a vision which he dislikes he must spit on his left three times, seek refuge in God from the devil three times, and turn from the side on which he was lying."Muslim transmitted it.
