Musnad Ahmad 27:1987

Abu Sa’id narrated to us, ‘Abd al-‘Aziz narrated to us, ‘Abdullah ibn Dinar narrated to us, from Ibn ‘Umar, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, for the treacherous person there is a banner on the Day of Resurrection. It is said: 'This is the treachery of so-and-so.'"
