At Tawbah, 80 Ayah
9:80
ٱسۡتَغۡفِرۡ لَهُمۡ أَوۡ لَا تَسۡتَغۡفِرۡ لَهُمۡ إِن تَسۡتَغۡفِرۡ لَهُمۡ سَبۡعِينَ مَرَّةٗ فَلَن يَغۡفِرَ ٱللَّهُ لَهُمۡۚ ذَٰلِكَ بِأَنَّهُمۡ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ ٨٠
Astaghfir Lahum 'Aw Lā Tastaghfir Lahum 'In Tastaghfir Lahum Sab`īna Marratan Falan Yaghfira Al-Lahu Lahum ۚ Dhālika Bi'annahum Kafarū Bil-Lahi Wa Rasūlihi Wa ۗ Allāhu Lā Yahdī Al-Qawma Al-Fāsiqīna
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.
