Regret and remorse in the Hereafter

وَقَالَ ٱلَّذِينَ ٱسْتُضْعِفُوا۟ لِلَّذِينَ ٱسْتَكْبَرُوا۟ بَلْ مَكْرُ ٱلَّيْلِ وَٱلنَّهَارِ إِذْ تَأْمُرُونَنَآ أَن نَّكْفُرَ بِٱللَّهِ وَنَجْعَلَ لَهُۥٓ أَندَادًا ۚ وَأَسَرُّوا۟ ٱلنَّدَامَةَ لَمَّا رَأَوُا۟ ٱلْعَذَابَ وَجَعَلْنَا ٱلْأَغْلَـٰلَ فِىٓ أَعْنَاقِ ٱلَّذِينَ كَفَرُوا۟ ۚ هَلْ يُجْزَوْنَ إِلَّا مَا كَانُوا۟ يَعْمَلُونَ

Those who were oppressed will say to those who were arrogant, "Rather, [it was your] conspiracy of night and day when you were ordering us to disbelieve in Allāh and attribute to Him equals." But they will [all] confide regret when they see the punishment; and We will put shackles on the necks of those who disbelieved. Will they be recompensed except for what they used to do?
