Az-Zumar (الزمر)
Chapter 39 - The Troops
أَن تَقُولَ نَفْسٌۭ يَٰحَسْرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِى جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّٰخِرِينَ
An taqoola nafsuny yaahasrataa 'alaa maa farrattu fee jambil laahi wa in kuntu laminas saakhireen
Lest a soul should say, "Oh [how great is] my regret over what I neglected in regard to Allah and that I was among the mockers."
Quran 39:56 - Surah Az-Zumar
وَأَنِيبُوٓا۟ إِلَىٰ رَبِّكُمْ وَأَسْلِمُوا۟ لَهُۥ مِن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ ثُمَّ لَا تُنصَرُونَ
And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped.
وَٱتَّبِعُوٓا۟ أَحْسَنَ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ بَغْتَةًۭ وَأَنتُمْ لَا تَشْعُرُونَ
And follow the best of what was revealed to you from your Lord before the punishment comes upon you suddenly while you do not perceive,
أَن تَقُولَ نَفْسٌۭ يَٰحَسْرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِى جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّٰخِرِينَ
Lest a soul should say, "Oh [how great is] my regret over what I neglected in regard to Allah and that I was among the mockers."
أَوْ تَقُولَ لَوْ أَنَّ ٱللَّهَ هَدَىٰنِى لَكُنتُ مِنَ ٱلْمُتَّقِينَ
Or [lest] it say, "If only Allah had guided me, I would have been among the righteous."
أَوْ تَقُولَ حِينَ تَرَى ٱلْعَذَابَ لَوْ أَنَّ لِى كَرَّةًۭ فَأَكُونَ مِنَ ٱلْمُحْسِنِينَ
Or [lest] it say when it sees the punishment, "If only I had another turn so I could be among the doers of good."
