﴿ وَيَقُولُونَ مَتَىٰ هَٰذَا ٱلْوَعْدُ إِن كُنتُمْ صَٰدِقِينَ ﴾

“And yet, they [who deny the truth] are wont to ask, "When is that promise [of resurrection and judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!"”

And they say ‘When will this promise of chastisement come to pass if you are truthful about it?’
