1. 3:117 مَثَلُ مَا يُنفِقُونَ فِى هَٰذِهِ ٱلْحَيَوٰةِ ٱلدُّنْيَا كَمَثَلِ رِيحٍ فِيهَا صِرٌّ أَصَابَتْ حَرْثَ قَوْمٍ ظَلَمُوٓا۟ أَنفُسَهُمْ فَأَهْلَكَتْهُ وَمَا ظَلَمَهُمُ ٱللَّهُ وَلَٰكِنْ أَنفُسَهُمْ يَظْلِمُونَ

   The likeness of what they spend in the life of this world is as the likeness of wind in which is intense cold (that) smites the seed produce of a people who haw done injustice to their souls and destroys it; and Allah is not unjust to them, but they are unjust to themselves.
   

2. 3:135 وَٱلَّذِينَ إِذَا فَعَلُوا۟ فَٰحِشَةً أَوْ ظَلَمُوٓا۟ أَنفُسَهُمْ ذَكَرُوا۟ ٱللَّهَ فَٱسْتَغْفَرُوا۟ لِذُنُوبِهِمْ وَمَن يَغْفِرُ ٱلذُّنُوبَ إِلَّا ٱللَّهُ وَلَمْ يُصِرُّوا۟ عَلَىٰ مَا فَعَلُوا۟ وَهُمْ يَعْلَمُونَ

   And those who when they commit an indecency or do injustice to their souls remember Allah and ask forgiveness for their faults-- and who forgives the faults but Allah, and (who) do not knowingly persist in what they have done.
   

3. 45:8 يَسْمَعُ ءَايَٰتِ ٱللَّهِ تُتْلَىٰ عَلَيْهِ ثُمَّ يُصِرُّ مُسْتَكْبِرًا كَأَن لَّمْ يَسْمَعْهَا فَبَشِّرْهُ بِعَذَابٍ أَلِيمٍ

   Who hears the communications of Allah recited to him, then persists proudly as though he had not heard them; so announce to him a painful punishment.
   

4. 51:29 فَأَقْبَلَتِ ٱمْرَأَتُهُۥ فِى صَرَّةٍ فَصَكَّتْ وَجْهَهَا وَقَالَتْ عَجُوزٌ عَقِيمٌ

   Then his wife came up in great grief, and she struck her face and said: An old barren woman!
   

5. 56:46 وَكَانُوا۟ يُصِرُّونَ عَلَى ٱلْحِنثِ ٱلْعَظِيمِ

   And they persisted in the great violation.
   

6. 71:7 وَإِنِّى كُلَّمَا دَعَوْتُهُمْ لِتَغْفِرَ لَهُمْ جَعَلُوٓا۟ أَصَٰبِعَهُمْ فِىٓ ءَاذَانِهِمْ وَٱسْتَغْشَوْا۟ ثِيَابَهُمْ وَأَصَرُّوا۟ وَٱسْتَكْبَرُوا۟ ٱسْتِكْبَارًا

   And whenever I have called them that Thou mayest forgive them, they put their fingers in their ears, cover themselves with their garments, and persist and are puffed up with pride:
