وَٱقْتَرَبَ ٱلْوَعْدُ ٱلْحَقُّ فَإِذَا هِىَ شَٰخِصَةٌ أَبْصَٰرُ ٱلَّذِينَ كَفَرُوا۟ يَٰوَيْلَنَا قَدْ كُنَّا فِى غَفْلَةٍۢ مِّنْ هَٰذَا بَلْ كُنَّا ظَٰلِمِينَ
And the True Promise draweth nigh; then behold them, staring wide (in terror), the eyes of those who disbelieve! (They say): Alas for us! We (lived) in forgetfulness of this. Ah, but we were wrong-doers!
Surah Al-Anbiyaa(21:97)
