قُلْ مَن كَانَ فِى ٱلضَّلَٰلَةِ فَلْيَمْدُدْ لَهُ ٱلرَّحْمَٰنُ مَدًّا ۚ حَتَّىٰٓ إِذَا رَأَوْا۟ مَا يُوعَدُونَ إِمَّا ٱلْعَذَابَ وَإِمَّا ٱلسَّاعَةَ فَسَيَعْلَمُونَ مَنْ هُوَ شَرٌّۭ مَّكَانًۭا وَأَضْعَفُ جُندًۭا
Say: As for him who is in error, the Beneficent will verily prolong his span of life until, when they behold that which they were promised, whether it be punishment (in the world), or the Hour (of doom), they will know who is worse in position and who is weaker as an army.
