Say, ˹O Prophet,˺ “Whoever is in error – the Most Compassionate will allow them plenty of time, until, when they are confronted with what they have been warned about- either the punishment [in this life] or the Hour [of Judgement]- they realize who is worse situated and who has the weakest forces.’
Meaning:-
Confronted: To come face to face with, especially with defiance or hostility, to face especially in challenge.
