167وَإِذ تَأَذَّنَ رَبُّكَ لَيَبعَثَنَّ عَلَيهِم إِلىٰ يَومِ القِيامَةِ مَن يَسومُهُم سوءَ العَذابِ ۗ إِنَّ رَبَّكَ لَسَريعُ العِقابِ ۖ وَإِنَّهُ لَغَفورٌ رَحيمٌT. B. IrvingSo your Lord announced that He would send someone against them who would impose the worst torment on them until Resurrection Day. Your Lord is Prompt with punishment, while He is (also) Forgiving, Merciful.
