Sahih al-Bukhari 7034
Narrated `Abdullah bin `Abbas:
Allah's Messenger (ﷺ) said, "While I was sleeping, two golden bangles were put in my two hands, so I got 
scared (frightened) and disliked it, but I was given permission to blow them off, and they flew away. I 
interpret it as a symbol of two liars who will appear." 'Ubaidullah said, "One of them was Al-`Ansi 
who was killed by Fairuz at Yemen and the other was Musailama (at Najd) .
فَقَالَ ابْنُ عَبَّاسٍ ذُكِرَ لِي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُ أَنَّهُ وُضِعَ فِي يَدَىَّ سِوَارَانِ مِنْ ذَهَبٍ، فَفُظِعْتُهُمَا وَكَرِهْتُهُمَا، فَأُذِنَ لِي، فَنَفَخْتُهُمَا فَطَارَا، فَأَوَّلْتُهُمَا كَذَّابَيْنِ يَخْرُجَانِ ‏"‏‏.‏ فَقَالَ عُبَيْدُ اللَّهِ أَحَدُهُمَا الْعَنْسِيُّ الَّذِي قَتَلَهُ فَيْرُوزٌ بِالْيَمَنِ، وَالآخَرُ مُسَيْلِمَةُ‏.‏
