﴿ أَوْ نُرِيَنَّكَ ٱلَّذِى وَعَدْنَٰهُمْ فَإِنَّا عَلَيْهِم مُّقْتَدِرُونَ ﴾

“and whether We show thee [or do not show thee in this world] the fulfillment of what We have promised them - verily, We have full power over them!”

or We show you during your lifetime that which We have promised them in the way of chastisement for surely We have power over surely We are able to chastise them.
