Sahih Bukhari Volume 5, Book 64, Hadith 4381

قَالَ عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ سَأَلْتُ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ عَنْ رُؤْيَا، رَسُولِ اللَّهِ صلى الله عليه وسلم الَّتِي ذَكَرَ فَقَالَ ابْنُ عَبَّاسٍ ذُكِرَ لِي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ بَيْنَا أَنَا نَائِمٌ أُرِيتُ أَنَّهُ وُضِعَ فِي يَدَىَّ سِوَارَانِ مِنْ ذَهَبٍ، فَفُظِعْتُهُمَا وَكَرِهْتُهُمَا، فَأُذِنَ لِي فَنَفَخْتُهُمَا فَطَارَا، فَأَوَّلْتُهُمَا كَذَّابَيْنِ يَخْرُجَانِ ‏"‏‏.‏ فَقَالَ عُبَيْدُ اللَّهِ أَحَدُهُمَا الْعَنْسِيُّ الَّذِي قَتَلَهُ فَيْرُوزُ بِالْيَمَنِ، وَالآخَرُ مُسَيْلِمَةُ الْكَذَّابُ‏

I asked Ibn Abbas about the dream Allah's Apostle had mentioned. Ibn Abbas said, "Someone told me that the Prophet said, "When I was sleeping, I saw in a dream that two gold bangles were put in my hands, and that frightened me and made me dislike them. Then I was allowed to blow on them, and when I blew at them, both of them flew. Then I interpreted them as two liars who would appear.' One of them was Al-'Ansi who was killed by Fairuz in Yemen and the other was Musailima Al-Kadhdbab."
