"I had a dream while sleeping as if there were two gold bracelets in my hands which bothered me very much. So it was reveled to me to blow them off. I blew them off and they flew away. I interpreted thwm to be two liars who would appear after me. One of them caled Masalamah of Yamamah, and (the other) Al-'ansi of San'a'." (sahih) (Using translation from Tirmidhī 2292)   

أَنَّ النَّبِيَّ ﷺ قَالَ «بَيْنَا أَنَا نَائِمٌ رَأَيْتُ فِي يَدِي سِوَارَيْنِ مِنْ ذَهَبٍ فَأَهَمَّنِي شَأْنُهُمَا فَأَوْحَى اللهُ إِلَيَّ فِي الْمَنَامِ أَنْفُخُهُمَا فَنَفَخْتُهُمَا فَطَارَا فَأَوَّلْتُهُمَا كَذَّابَيْنِ يَخْرُجَانِ بَعْدِي» وَكَانَ أَحَدُهُمَا الْعَنْسِيَّ صَاحِبَ صَنْعَاءَ وَالْآخَرُ مُسَيْلِمَةُ صَاحِبُ الْيَمَامَةِ
