Surah Al-Araf Verse 167 - English Translation by Edward Henry Palmer
Surah Al-Arafوَإِذۡ تَأَذَّنَ رَبُّكَ لَيَبۡعَثَنَّ عَلَيۡهِمۡ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ مَن يَسُومُهُمۡ سُوٓءَ ٱلۡعَذَابِۗ إِنَّ رَبَّكَ لَسَرِيعُ ٱلۡعِقَابِ وَإِنَّهُۥ لَغَفُورٞ رَّحِيمٞ
and then thy Lord proclaimed that He would surely send against them till the resurrection day, those who should wreak them evil torment; verily, thy Lord is quick at following up, but, verily, He is forgiving, merciful
