Musnad Ahmad 26:409

Sulayman ibn Dawud narrated to us, Shu'bah informed us, from al-A'mash, who heard Abu Wa'il narrating from 'Abdullah, from the Prophet, may Allah bless him and grant him peace, that he said: "For every treacherous person there is a banner, and it will be said: 'This is the treachery of so-and-so.'"
