The Quran

وَاقتَرَبَ الوَعدُ الحَقُّ فَإِذا هِيَ شاخِصَةٌ أَبصارُ الَّذينَ كَفَروا يا وَيلَنا قَد كُنّا في غَفلَةٍ مِن هٰذا بَل كُنّا ظالِمينَ

Muhammad Asad

the while the true promise [of resurrection] draws close [to its fulfilment]. But then, lo! the eyes of those who [in their lifetime] were bent on denying the truth will stare in horror, [and they will exclaim:] "Oh, woe unto us! We were indeed heedless of this [promise of resurrection]! - nay, we were [bent on] doing evil!"¹

I.e., deliberately and without any excuse, since all the prophets had warned man of the Day of Resurrection and Judgment: cf. 14:44-45. The words "bent on" interpolated by me within brackets indicate intent, similar to the preceding expression alladhina kafaru, "those who were bent on denying the truth" (see also note 6 on 2:6).
