وَإِذْ تَأَذَّنَ رَبُّكَ لَيَبْعَثَنَّ عَلَيْهِمْ إِلَىٰ يَوْمِ ٱلْقِيَـٰمَةِ مَن يَسُومُهُمْ سُوٓءَ ٱلْعَذَابِ ۗ إِنَّ رَبَّكَ لَسَرِيعُ ٱلْعِقَابِ ۖ وَإِنَّهُۥ لَغَفُورٌ رَّحِيمٌ
wa-idh ta-adhana rabbuka layabʿathanna ʿalayhim ilā yawmi l-qiyāmati man yasūmuhum sūa l-ʿadhābi inna rabbaka lasarīʿu l-ʿiqābi wa-innahu laghafūrun raḥīmun
And then your Lord declared that, until the Day of Resurrection, He would send people against them to inflict terrible suffering on them. Your Lord is swift in punishment but He is most forgiving and merciful.
And (remember) when your Lord declared that He would certainly keep on sending against them (i.e. the Jews), till the Day of Resurrection, those who would afflict them with a humiliating torment. Verily, your Lord is Quick in Retribution (for the disobedient, wicked) and certainly He is Oft-Forgiving, Most Merciful (for the obedient and those who beg Allâh’s Forgiveness).
