Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Ibn ‘Umar (Radi-Allahu ‘anhu):
Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam) 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) of so-and-so, the son of so-and-so.’ ”
