Sura 9 At-Tawba (Il Pentimento o la Disapprovazione), versetto 80

1. اسْتَغْفِرْ لَهُمْ أَوْ لَا تَسْتَغْفِرْ لَهُمْ إِنْ تَسْتَغْفِرْ لَهُمْ سَبْعِينَ مَرَّةً فَلَنْ يَغْفِرَ اللَّهُ لَهُمْ ۚ ذَٰلِكَ بِأَنَّهُمْ كَفَرُوا بِاللَّهِ وَرَسُولِهِ ۗ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْفَاسِقِينَ

   Ask forgiveness for them, (O Muhammad), or do not ask forgiveness for them. If you should ask forgiveness for them seventy times - never will Allah forgive them. That is because they disbelieved in Allah and His Messenger, and Allah does not guide the defiantly disobedient people.

   9:80
