7 : 167
وَإِذۡ تَأَذَّنَ رَبُّكَ لَيَبۡعَثَنَّ عَلَيۡهِمۡ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ مَن يَسُومُهُمۡ سُوٓءَ ٱلۡعَذَابِۗ إِنَّ رَبَّكَ لَسَرِيعُ ٱلۡعِقَابِ وَإِنَّهُۥ لَغَفُورٞ رَّحِيمٞ
And [remember] when your Lord declared that He would send against them those who would afflict them with a terrible punishment until the Day of Resurrection. Your Lord is Swift in Punishment, but He also is All-Forgiving, Most Merciful.
