وَلَئِنْ أَخَّرْنَا عَنْهُمُ ٱلْعَذَابَ إِلَىٰٓ أُمَّةٍۢ مَّعْدُودَةٍۢ لَّيَقُولُنَّ مَا يَحْبِسُهُۥٓ ۗ أَلَا يَوْمَ يَأْتِيهِمْ لَيْسَ مَصْرُوفًا عَنْهُمْ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ
And if We delay for them the doom until a reckoned time, they will surely say: What withholdeth it? Verily on the day when it cometh unto them, it cannot be averted from them, and that which they derided will surround them.
