ٱسْتَغْفِرْ لَهُمْ أَوْ لَا تَسْتَغْفِرْ لَهُمْ إِن تَسْتَغْفِرْ لَهُمْ سَبْعِينَ مَرَّةً فَلَن يَغْفِرَ ٱللَّهُ لَهُمْ ۚ ذَٰلِكَ بِأَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَرَسُولِهِۦ ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْفَـٰسِقِينَ

Whether you (O dear Prophet Mohammed – peace and blessings be upon him) ask forgiveness for them* or not ask forgiveness for them; even if you ask forgiveness for them seventy times, Allah will not forgive them; that is because they disbelieved in Allah and His Noble Messenger, and Allah does not guide the sinful. (* for the hypocrites.) - Ahmed Raza Khan (English)
