﴿ إِنَّآ أَنذَرْنَٰكُمْ عَذَابًۭا قَرِيبًۭا يَوْمَ يَنظُرُ ٱلْمَرْءُ مَا قَدَّمَتْ يَدَاهُ وَيَقُولُ ٱلْكَافِرُ يَٰلَيْتَنِى كُنتُ تُرَٰبًۢا ﴾

“Verily, We have warned you of suffering near at hand - [suffering] on the Day when man shall [clearly] see what his hands have sent ahead, and when he who has denied the truth shall say, "Oh, would that I were mere dust...!"”

Lo! We have warned you O disbelievers of Mecca of a chastisement that is near the chastisement of the impending Day of Resurrection — for anything that is impending is also near — the day yawma adverbially qualifies ‘adhāban ‘a chastisement’ by describing it when a person when every person will behold what his hands have sent ahead of good and evil and the disbeliever will say ‘O yā is a particle used to call attention to something would that I were dust!’ in other words and not be chastised. He says this when God exalted be He says to the beasts after each of them has retaliated against the other ‘Be dust!’.
