And Abu Bakr ibn Abi Shaybah narrated to us, Yahya ibn Adam narrated to us, from Yazid ibn 'Abd al-'Aziz, from al-A'mash, from Shaqiq, from 'Abdullah, who said: The Messenger of Allah (peace and blessings be upon him) said: "Every traitor will have a banner on the Day of Resurrection, by which he will be recognized. It will be said: 'This is the treachery of so-and-so.'"
