When Allah gathers the first and the last on the Day of Judgment, a banner will be raised for every traitor, and it will be said: This is the betrayal of so-and-so, the son of so-and-so

The Prophet (may Allah's peace and blessings be upon him) informs that on the Day of Judgment, when Allah Almighty gathers the first and the last for the reckoning, He will set up a sign for every traitor who failed to fulfill a covenant he made, whether with Allah or with people. This sign will expose his betrayal, and he will be called out on that day: This is the betrayal of so-and-so, the son of so-and-so, to expose the evil of his deed before the people of the Gathering.
