Abu Huraira reported Allah's Messenger ﷺ as saying

“While I was asleep I was brought the treasures of the earth, and two bracelets of gold which were placed in my hands weighed upon me. Then it was revealed to me that I should blow on them, and when I did so they departed. I interpreted them as representing the two liars between whom I am placed, the one in San'a' and the one in al-Yamama.” (Bukhari and Muslim.) A version says that one of them was Musailima,* the man in al-Yamama, and the other al-‘Ansi,** the man in San'a’. I (the translator) have not found this version in the two Sahihs, but the author of the Jami' mentioned it on Tirmidhi’s authority. * He set himself up as a prophet. ** Al-Aswad al-'Ansi who attacked al-Muhajir b. Abu Umayya b. Al-Mughira, the Prophet’s agent sent to San'a' to collect sadaqat. He caused a considerable insurrection in the south.
