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

“And Abraham's prayer that his father be forgiven was but due to a promise which he had given the latter [in his lifetime]; but when it was made clear unto him that he had been God's enemy, [Abraham] disavowed him - [although;] behold, Abraham was most tender-hearted. most clement.”

Abraham’s prayer for the forgiveness of his father was only because of a promise he had made to him when he said to him I will ask my Lord forgiveness for you Q. 1947 in the hope that he would submit to God; but when it became clear to him that he was an enemy of God upon his death as an disbeliever he declared himself innocent of him and refrained from asking forgiveness for him; truly Abraham was soft of heart making frequent entreaty and supplication to God forbearing enduring harm patiently.
