question #3 Sahih al-Bukhari 6178, Book 78, Hadith 202 : What significance does the concept of a flag hold in relation to betrayal in Islamic eschatology?

Allah’s Messenger (ﷺ) said, “A flag will be fixed on the Day of Resurrection for every betrayer, and it will be
announced (publicly in front of everybody), ‘This is the betrayal (perfidy) so-and-so, the son of soand-
so.”
