9:80
اِسۡتَغۡفِرۡ لَهُمۡ اَوۡ لَا تَسۡتَغۡفِرۡ لَهُمۡؕ اِنۡ تَسۡتَغۡفِرۡ لَهُمۡ سَبۡعِيۡنَ مَرَّةً فَلَنۡ يَّغۡفِرَ اللّٰهُ لَهُمۡؕ ذٰلِكَ بِاَنَّهُمۡ كَفَرُوۡا بِاللّٰهِ وَرَسُوۡلِهٖؕ وَاللّٰهُ لَا يَهۡدِي الۡقَوۡمَ الۡفٰسِقِيۡنَࣖ
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
