Chapter 58: Jizyah and Mawaada'ah
Narrated Anas: The Prophet (ﷺ) said, '' Every betrayer will have a flag on the Day of Resurrection" One of the two subnarrators
said that the flag would be fixed, and the other said that it would be shown on the Day of
Resurrection, so that the betrayer might be recognized by it.
