Musnad Ahmad 31:361

Mu'awiyah ibn Hisham narrated to us, he said: Shayban narrated to us, from Firas, from 'Atiyyah, from Abu Sa'id, from the Messenger of Allah, peace and blessings of Allah be upon him, who said: "A banner will be raised for the treacherous person on the Day of Resurrection because of his treachery, and it will be said: 'This is the banner of the treachery of so-and-so.'"
