﴿ وَعُرِضُوا۟ عَلَىٰ رَبِّكَ صَفًّۭا لَّقَدْ جِئْتُمُونَا كَمَا خَلَقْنَٰكُمْ أَوَّلَ مَرَّةٍۭ ۚ بَلْ زَعَمْتُمْ أَلَّن نَّجْعَلَ لَكُم مَّوْعِدًۭا ﴾

“And they will be lined up before thy Sustainer, [and He will say:] "Now, indeed, you have come unto Us [in a lonely state], even as We created you in the first instances - although you were wont to assert that We would never 'appoint for you a meeting [with Us]!"”
