وَمَا كَانَ ٱسْتِغْفَارُ إِبْرَٰهِيمَ لِأَبِيهِ إِلَّا عَن مَّوْعِدَةٍ وَعَدَهَآ إِيَّاهُ فَلَمَّا تَبَيَّنَ لَهُۥٓ أَنَّهُۥ عَدُوٌّ لِّلَّهِ تَبَرَّأَ مِنْهُ إِنَّ إِبْرَٰهِيمَ لَأَوَّٰهٌ حَلِيمٌ
Saheeh International(114) And the request of forgiveness of Abraham for his father was only because of a promise he had made to him. But when it became apparent to him [i.e., Abraham] that he [i.e., the father] was an enemy to Allāh, he disassociated himself from him. Indeed was Abraham compassionate and patient.
