وَاقْتَرَبَ الْوَعْدُ الْحَقُّ فَاِذَا هِيَ شَاخِصَةٌ اَبْصَارُ الَّذِيْنَ كَفَرُوْاۗ يٰوَيْلَنَا قَدْ كُنَّا فِيْ غَفْلَةٍ مِّنْ هٰذَا بَلْ كُنَّا ظٰلِمِيْنَ ( الأنبياء: ٩٧ )
Waqtarabal wa'dul haqqu fa-izaa hiya shaakhisatun absaarul lazeena kafaroo yaawailanaa qad kunna fee ghaflatim min haaza bal kunnaa zaalimeen (al-ʾAnbiyāʾ 21:97)
Sahih International:
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." (Al-Anbya [21] : 97)
1 Mufti Taqi Usmani
and the True Promise draws near, then it will so happen that the eyes of the disbelievers shall remain upraised (in terror, and they will say,) “Alas to us! We were in negligence about this; rather we were transgressors.”
