9:114
وَمَا كَانَ ٱسْتِغْفَارُ إِبْرَٰهِيمَ لِأَبِيهِ إِلَّا عَن مَّوْعِدَةٍ وَعَدَهَآ إِيَّاهُ فَلَمَّا تَبَيَّنَ لَهُۥٓ أَنَّهُۥ عَدُوٌّ لِّلَّهِ تَبَرَّأَ مِنْهُ ۚ إِنَّ إِبْرَٰهِيمَ لَأَوَّٰهٌ حَلِيمٌ
9:114
And Abraham's prayer for the forgiveness of his father was only because of a promise which he had made to him. Then, when it became clear to him that he was an enemy of Allah, he dissociated himself from him. Surely Abraham was most tender-hearted, God-fearing, forbearing. - Abul Ala Maududi (English)
