"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)
