Musnad Ahmad 30:1340

Yunus narrated to us, Hammad narrated to us, from Muhammad ibn Amr, from Abu Salamah, from Abu Hurairah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "I saw in what the sleeper sees, as if there were two bracelets of gold in my hands. I blew upon them, and they fell away. So I interpreted them to be Musaylimah and the other to be al-Ansi."
