Mukhtasar Bukhari (Abridged) 1688 — The story of the envoys of Banu

Narrated Abu Huraira (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: "I was sleeping when the treasures of the earth were brought to me, and two gold bangles were placed in my hands. I disliked this, so it was revealed to me that I should blow on them. When I blew on them, they both flew away. I interpreted this as referring to two liars between whom I am, both of them being the one from Sana'a (i.e., Aswad Ansi) and the one from Yamama (Musaylimah the liar)."
