Sahih Muslim Book - 42, Hadith - 5903

حَدَّثَنَا أَبُو بَكْرِ بْنُ خَلاَّدٍ الْبَاهِلِيُّ ، وَأَحْمَدُ بْنُ عَبْدِ اللهِ بْنِ الْحَكَمِ ، قَالاَ : حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَبْدِ رَبِّهِ بْنِ سَعِيدٍ ، عَنْ أَبِي سَلَمَةَ ، قَالَ : إِنْ كُنْتُ لأَرَى الرُّؤْيَا تُمْرِضُنِي ، قَالَ : فَلَقِيتُ أَبَا قَتَادَةَ ، فَقَالَ : وَأَنَا كُنْتُ لأَرَى الرُّؤْيَا فَتُمْرِضُنِي ، حَتَّى سَمِعْتُ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ : الرُّؤْيَا الصَّالِحَةُ مِنَ اللهِ ، فَإِذَا رَأَى أَحَدُكُمْ مَا يُحِبُّ ، فَلاَ يُحَدِّثْ بِهَا إِلاَّ مَنْ يُحِبُّ ، وَإِنْ رَأَى مَا يَكْرَهُ فَلْيَتْفُلْ عَنْ يَسَارِهِ ثَلاَثًا وَلْيَتَعَوَّذْ بِاللَّهِ مِنْ شَرِّ الشَّيْطَانِ وَشَرِّهَا ، وَلاَ يُحَدِّثْ بِهَا أَحَدًا فَإِنَّهَا لَنْ تَضُرَّهُ.

It was narrated that Abu Salamah said: “I used to see dreams that made me ill. Then I met Abu Qatadah and he said: ‘I used to see dreams that made me ill, until I heard the Messenger of Allah (s.a.w) say: “Good dreams come from Allah, so if one of you sees something that he likes, let hum not tell anyone of it but one whom he loves. If he sees something that he dislikes, let him spit lightly to his left three times, and seek refuge with Allah from the evil if the Shaitan and its evil, but let him not tell anyone about it, for it will not harm him.”’
