The Prophet ﷺ said, "If anyone of you sees a dream that he likes, then it is from Allah, and he should thank Allah for it and narrate it to others; but if he sees something else, i.e., a dream that he dislikes, then it is from Satan, and he should seek refuge with Allah from its evil, and he should not mention it to anybody, for it will not harm him." (Using translation from Bukhārī 6985)  

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا رَأَى أَحَدُكُمُ الرُّؤْيَا يُحِبُّهَا فَإِنَّمَا هِيَ مِنَ اللهِ فَلْيَحْمَدِ اللهَ عَلَيْهَا وَلْيُحَدِّثْ بِهَا وَإِذَا رَأَى غَيْرَ ذَلِكَ مِمَّا يَكْرَهُهُ فَإِنَّمَا هِيَ مِنَ الشَّيْطَانِ فَلْيَسْتَعِذْ بِاللهِ مِنْ شَرِّهَا وَلَا يَذْكُرْهَا لِأَحَدٍ فَإِنَّهَا لَا تَضُرُّهُ»
