﴿ 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.”

(The prayer of Abraham for the forgiveness of his father was only because of a promise he had promised him) that he would surrender, (but when it had become clear unto him that he (his father) was an enemy to Allah) that he had died an unbeliever (he (Abraham) disowned him) and his religion. (Lo! Abraham was soft of heart) in the face of ignorance, (long-suffering) compassionate; it is also said that Abraham used to complain about fire even before being thrown in it.
