I asked Ibn Abbas about the dream of Messenger of Allah which he mentioned. (see following hadith)  

عَنْ رُؤْيَا رَسُولِ اللَّهِ ﷺ الَّتِي ذَكَرَ  

Messenger of Allah 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-ʿAnsi who was killed by Fairuz at Yemen and the other was Musailama (at Najd) .  

أَنَّ رَسُولَ اللَّهِ ﷺ 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
