Al-Mukhtasar
وَٱقْتَرَبَ ٱلْوَعْدُ ٱلْحَقُّ فَإِذَا هِىَ شَـٰخِصَةٌ أَبْصَـٰرُ ٱلَّذِينَ كَفَرُوا۟ يَـٰوَيْلَنَا قَدْ كُنَّا فِى غَفْلَةٍ مِّنْ هَـٰذَا بَلْ كُنَّا ظَـٰلِمِينَ ﴿٩٧﴾
Their emergence, terror and violence will be a sign of the rising drawing nearer. The disbelievers will be left wide-eyed in horror, saying: Oh my, what a destruction faces us! We were indulged in futility in the world, preoccupied from preparing for this severe day. Rather, we were wrongdoers by disbelieving and committing sins.
