Musnad Abu Ya'la al-Mawsili 155:54

Ibrahim ibn Sa'id al-Jawhari narrated to us, Abu al-Yaman narrated to us, Shu'ayb narrated to us, 'Abdullah ibn Abi Husayn narrated to us, from Nafi' ibn Jubayr, from Ibn 'Abbas, that Abu Hurayrah informed him that the Prophet (ﷺ) said: "While I was sleeping, I saw in what a sleeper sees two bracelets of gold, and their matter concerned me. He said: While I was sleeping, it was revealed to me that I should blow upon them, so I blew upon them and they flew away. I interpreted them as two liars who would emerge. One of them was al-'Ansi, the master of San'a, and the other was Musaylimah."
