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 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. - Mohammad Habib Shakir (English)
