Istighfar for the Pagans

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

Whether thou ask for their forgiveness, or not, (their sin is unforgivable): if thou ask seventy times for their forgiveness, Allah will not forgive them: because they have rejected Allah and His Messenger: and Allah guideth not those who are perversely rebellious.

مَا كَانَ لِلنَّبِىِّ وَٱلَّذِينَ ءَامَنُوٓا۟ أَن يَسْتَغْفِرُوا۟ لِلْمُشْرِكِينَ وَلَوْ كَانُوٓا۟ أُو۟لِى قُرْبَىٰ مِنۢ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَٰبُ ٱلْجَحِيمِ

It is not fitting, for the Prophet and those who believe, that they should pray for forgiveness for Pagans, even though they be of kin, after it is clear to them that they are companions of the Fire.

وَمَا كَانَ ٱسْتِغْفَارُ إِبْرَٰهِيمَ لِأَبِيهِ إِلَّا عَن مَّوْعِدَةٍۢ وَعَدَهَآ إِيَّاهُ فَلَمَّا تَبَيَّنَ لَهُۥٓ أَنَّهُۥ عَدُوٌّۭ لِّلَّهِ تَبَرَّأَ مِنْهُ ۚ إِنَّ إِبْرَٰهِيمَ لَأَوَّٰهٌ حَلِيمٌۭ

And Abraham prayed for his father's forgiveness only because of a promise he had made to him. But when it became clear to him that he was an enemy to Allah, he dissociated himself from him: for Abraham was most tender-hearted, forbearing.
