Surat At-Tawba (The Repentance) - التوبة

مَا كَانَ لِلنَّبِىِّ وَٱلَّذِينَ ءَامَنُوٓا۟ أَن يَسْتَغْفِرُوا۟ لِلْمُشْرِكِينَ وَلَوْ كَانُوٓا۟ أُو۟لِى قُرْبَىٰ مِنۢ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَٰبُ ٱلْجَحِيمِ ﴿١١٣﴾ وَمَا كَانَ ٱسْتِغْفَارُ إِبْرَٰهِيمَ لِأَبِيهِ إِلَّا عَن مَّوْعِدَةٍ وَعَدَهَآ إِيَّاهُ فَلَمَّا تَبَيَّنَ لَهُۥٓ أَنَّهُۥ عَدُوٌّ لِّلَّهِ تَبَرَّأَ مِنْهُ إِنَّ إِبْرَٰهِيمَ لَأَوَّٰهٌ حَلِيمٌ﴿١١٤﴾

It is not (fit) for the Prophet and those who believe that they should ask forgiveness for the polytheists, even though they should be near relatives, after it has become clear to them that they are inmates of the flaming fire. And Ibrahim asking forgiveness for his sire was only owing to a promise which he had made to him; but when it became clear to him that he was an enemy of Allah, he declared himself to be clear of him; most surely Ibrahim was very tender-hearted forbearing.
