Surah Al-Anbiya' (The Prophets), Verse 97

وَاقْتَرَبَ الْوَعْدُ الْحَقُّ فَاِذَا هِیَ شَاخِصَةٌ اَبْصَارُ الَّذِیْنَ كَفَرُوْا یٰوَیْلَنَا قَدْ كُنَّا فِیْ غَفْلَةٍ مِّنْ هٰذَا بَلْ كُنَّا ظٰلِمِیْنَ ۟

Waqtarabal wa'dul haqqu fa-izaa hiya shaakhisatun absaarul lazeena kafaroo yaawailanaa qad kunna fee ghaflatin min haaza bal kunnaa zaalimeen

“Then will the true promise draw nigh (of fulfilment): then behold! the eyes of the Unbelievers will fixedly stare in horror: "Ah! Woe to us! we were indeed heedless of this; nay, we truly did wrong!"”
