Al ‘Ankabut Ayah 53

وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ‌ۚ وَلَوْلَآ أَجَلٌ مُّسَمًّى لَّجَآءَهُمُ ٱلْعَذَابُ وَلَيَأْتِيَنَّهُم بَغْتَةً وَهُمْ لَا يَشْعُرُونَ ٥٣ They challenge you ?O Prophet? to hasten the punishment. Had it not been for a time already set, the punishment would have certainly come to them ?at once?. But it will definitely take them by surprise when they least expect it.
