regret

فَلَمَّا رَأَوْهَا قَالُوٓا۟ إِنَّا لَضَآلُّونَ

But when they saw it, they said, "Indeed, we are lost;

قَالَ أَوْسَطُهُمْ أَلَمْ أَقُل لَّكُمْ لَوْلَا تُسَبِّحُونَ

The most moderate of them said, "Did I not say to you, 'Why do you not exalt [Allāh]?'"

فَأَقْبَلَ بَعْضُهُمْ عَلَىٰ بَعْضٍ يَتَلَـٰوَمُونَ

Then they approached one another, blaming each other.

خَـٰشِعَةً أَبْصَـٰرُهُمْ تَرْهَقُهُمْ ذِلَّةٌ ۖ وَقَدْ كَانُوا۟ يُدْعَوْنَ إِلَى ٱلسُّجُودِ وَهُمْ سَـٰلِمُونَ

Their eyes humbled, humiliation will cover them. And they used to be invited to prostration while they were sound.

وَأَمَّا مَنْ أُوتِىَ كِتَـٰبَهُۥ بِشِمَالِهِۦ فَيَقُولُ يَـٰلَيْتَنِى لَمْ أُوتَ كِتَـٰبِيَهْ

But as for he who is given his record in his left hand, he will say, "Oh, I wish I had not been given my record

وَلَمْ أَدْرِ مَا حِسَابِيَهْ

And had not known what is my account.

يَـٰلَيْتَهَا كَانَتِ ٱلْقَاضِيَةَ

I wish it [i.e., my death] had been the decisive one.

مَآ أَغْنَىٰ عَنِّى مَالِيَهْ ۜ

My wealth has not availed me.

هَلَكَ عَنِّى سُلْطَـٰنِيَهْ

Gone from me is my authority."

وَإِنَّهُۥ لَحَسْرَةٌ عَلَى ٱلْكَـٰفِرِينَ

And indeed, it will be [a cause of] regret upon the disbelievers.

يُبَصَّرُونَهُمْ ۚ يَوَدُّ ٱلْمُجْرِمُ لَوْ يَفْتَدِى مِنْ عَذَابِ يَوْمِئِذٍۭ بِبَنِيهِ

They will be shown each other. The criminal will wish that he could be ransomed from the punishment of that Day by his children.

قَالُوا۟ لَمْ نَكُ مِنَ ٱلْمُصَلِّينَ

They will say, "We were not of those who prayed,

وَكُنَّا نَخُوضُ مَعَ ٱلْخَآئِضِينَ

And we used to enter into vain discourse with those who engaged [in it],

وَكُنَّا نُكَذِّبُ بِيَوْمِ ٱلدِّينِ

And we used to deny the Day of Recompense

حَتَّىٰٓ أَتَىٰنَا ٱلْيَقِينُ

Until there came to us the certainty [i.e., death]."

إِنَّآ أَنذَرْنَـٰكُمْ عَذَابًا قَرِيبًا يَوْمَ يَنظُرُ ٱلْمَرْءُ مَا قَدَّمَتْ يَدَاهُ وَيَقُولُ ٱلْكَافِرُ يَـٰلَيْتَنِى كُنتُ تُرَٰبًۢا

Indeed, We have warned you of an impending punishment on the Day when a man will observe what his hands have put forth and the disbeliever will say, "Oh, I wish that I were dust!"

فَسَوْفَ يَدْعُوا۟ ثُبُورًا

He will cry out for destruction

وَجِا۟ىٓءَ يَوْمَئِذٍۭ بِجَهَنَّمَ ۚ يَوْمَئِذٍ يَتَذَكَّرُ ٱلْإِنسَـٰنُ وَأَنَّىٰ لَهُ ٱلذِّكْرَىٰ

And brought [within view], that Day, is Hell - that Day, man will remember, but how [i.e., what good] to him will be the remembrance?

يَقُولُ يَـٰلَيْتَنِى قَدَّمْتُ لِحَيَاتِى

He will say, "Oh, I wish I had sent ahead [some good] for my life."
