The Day of Judgment and its horrors

وَٱقْتَرَبَ ٱلْوَعْدُ ٱلْحَقُّ فَإِذَا هِىَ شَـٰخِصَةٌ أَبْصَـٰرُ ٱلَّذِينَ كَفَرُوا۟ يَـٰوَيْلَنَا قَدْ كُنَّا فِى غَفْلَةٍ مِّنْ هَـٰذَا بَلْ كُنَّا ظَـٰلِمِينَ

And [when] the true promise [i.e., the resurrection] has approached; then suddenly the eyes of those who disbelieved will be staring [in horror, while they say], "O woe to us; we had been unmindful of this; rather, we were wrongdoers."
