وَإِذْ And when تَأَذَّنَ declared رَبُّكَ your Lord لَيَبْعَثَنَّ that He would surely send عَلَيْهِمْ upon them إِلَىٰ till يَوْمِ (the) Day ٱلْقِيَـٰمَةِ (of) the Resurrection مَن (those) who يَسُومُهُمْ would afflict them سُوٓءَ (with) a grievous ٱلْعَذَابِ ۗ [the] punishment إِنَّ Indeed رَبَّكَ your Lord لَسَرِيعُ (is) surely swift ٱلْعِقَابِ ۖ (in) the retribution وَإِنَّهُۥ but indeed, He لَغَفُورٌۭ (is) surely Oft-Forgiving رَّحِيمٌۭ Most Merciful ١٦٧
And [mention] when your Lord declared that He would surely [continue to] send upon them until the Day of Resurrection those who would afflict them with the worst torment. Indeed, your Lord is swift in penalty; but indeed, He is Forgiving and Merciful.
