persistence in error despite opportunity for repentance

وَحَسِبُوٓا۟ أَلَّا تَكُونَ فِتْنَةٌ فَعَمُوا۟ وَصَمُّوا۟ ثُمَّ تَابَ ٱللَّهُ عَلَيْهِمْ ثُمَّ عَمُوا۟ وَصَمُّوا۟ كَثِيرٌ مِّنْهُمْ ۚ وَٱللَّهُ بَصِيرٌۢ بِمَا يَعْمَلُونَ

And they thought there would be no [resulting] punishment, so they became blind and deaf. Then Allāh turned to them in forgiveness; then [again] many of them became blind and deaf. And Allāh is Seeing of what they do.
