وَٱتَّبِعُوٓا۟ أَحْسَنَ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ بَغْتَةًۭ وَأَنتُمْ لَا تَشْعُرُونَ ﴿٥٥﴾
And follow the best of what was revealed to you from your Lord [i.e., the Qur’ān] before the punishment comes upon you suddenly while you do not perceive,
أَن تَقُولَ نَفْسٌۭ يَـٰحَسْرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِى جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّـٰخِرِينَ ﴿٥٦﴾
Lest a soul should say, "Oh, [how great is] my regret over what I neglected in regard to Allāh and that I was among the mockers."
أَوْ تَقُولَ لَوْ أَنَّ ٱللَّهَ هَدَىٰنِى لَكُنتُ مِنَ ٱلْمُتَّقِينَ ﴿٥٧﴾
Or [lest] it say, "If only Allāh had guided me, I would have been among the righteous."
أَوْ تَقُولَ حِينَ تَرَى ٱلْعَذَابَ لَوْ أَنَّ لِى كَرَّةًۭ فَأَكُونَ مِنَ ٱلْمُحْسِنِينَ ﴿٥٨﴾
Or [lest] it say when it sees the punishment, "If only I had another turn so I could be among the doers of good."
بَلَىٰ قَدْ جَآءَتْكَ ءَايَـٰتِى فَكَذَّبْتَ بِهَا وَٱسْتَكْبَرْتَ وَكُنتَ مِنَ ٱلْكَـٰفِرِينَ ﴿٥٩﴾
But yes, there had come to you My verses, but you denied them and were arrogant, and you were among the disbelievers.
