Indeed, We have warned you of a near punishment on the Day (78:40)

Almuntakhab Fi Tafsir Alquran Alkarim

We have warned you of punishment evident and quite near that deserves attention. On the day it comes to pass shall every one look at his deeds, the lawful and the lawless which his wrongful and unclean hands had committed. The infidel shall wish, then, he had remained mere dust

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(78:40) Lo! We warn you of a chastisement near at hand; *26 the Day when a man will look on what his own hands have sent forth, and the unbelievers shall say: 'Oh would that I were utter dust.' *27

Indeed, We have warned you of a near punishment on the Day meaning

*26) Apparently, one might think that the people who were the audience of this verse died fourteen centuries ago, ,and even now it cannot be said how many hundreds or thousands or millions of years Resurrection will take to come. Then, in what sense has it been said: "The torment of which you have been warned, has approached near at hand?" And what is the meaning of saying in the beginning of the Surah: "Soon they shall know?" The answer is that man can have the feeling of time only until he is passing a physical life in the world within the bounds of space and time. After death when only the soul will survive, he will lose every feeling and consciousness of time, and on the Day of Resurrection when man will rise back to life, he will feel as though some one had aroused him from sleep suddenly. He will not at all be conscious that he has been resurrected after thousands of years. (For further explanation, see E.N. 26 of An-Nahl, E.N. 56 of Bani Isra'il, E.N. 80 of Ta Ha, E.N. 48 of Ya Sin).
*27) "Would ......dust": "Would that I had not been born in the world, or had become mere dust after death, and thus reduced to nothingness."

ہم نے تم لوگوں کو اُس عذاب سے ڈرا دیا ہے جو قریب آ لگا ہے جس روز آدمی وہ سب کچھ دیکھ لے گا جو اس کے ہاتھوں نے آگے بھیجا ہے، اور کافر پکار اٹھے گا کہ کاش میں خاک ہوتا
