Surah At-Tawbah, Verse 80

ٱسۡتَغۡفِرۡ لَهُمۡ أَوۡ لَا تَسۡتَغۡفِرۡ لَهُمۡ إِن تَسۡتَغۡفِرۡ لَهُمۡ سَبۡعِينَ مَرَّةٗ فَلَن يَغۡفِرَ ٱللَّهُ لَهُمۡۚ ذَٰلِكَ بِأَنَّهُمۡ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ٨٠

is'taghfir lahum aw lā tastaghfir lahum in tastaghfir lahum sabʿīna marratan falan yaghfira l-lahu lahum dhālika bi-annahum kafarū bil-lahi warasūlihi wal-lahu lā yahdī l-qawma l-fāsiqīna

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