It has been narrated on the authority of Ibn 'Umar that the Messenger of Allah (ﷺ) said:When Allah will gather together, on the Day of Judgment, all the earlier and later generations of mankind, a flag will be raised (to mark off) every person guilty of breach of faith, and it will be announced that this is the perfidy of so and so, son of so and so (to attract the attention of people to his guilt)
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
