﴿ يَوْمَ نَبْطِشُ ٱلْبَطْشَةَ ٱلْكُبْرَىٰٓ إِنَّا مُنتَقِمُونَ ﴾

“on the Day when We shall seize [all sinners] with a most mighty onslaught, We shall, verily, inflict Our retribution [on you as well]!”

This is because He said: (On the day when We shall seize them with the greater seizure) We shall punish them with the greater punishment, by the sword on the Day of Badr ((then), in truth We shall punish) with Our torment.
