"I heard a man praying for forgiveness for his parents who were idolaters, and I said: 'Are you praying for forgiveness for them even though they are idolators?" He said: 'Didn't Ibrahim pray for forgiveness for his father?' I went to the Prophet and told him about that, then the following revealed: And Ibrahim's (Abraham) invoking (of Allah) for his father's forgiveness was only because of a promise he (Ibrahim) had made to him (his father)."

سَمِعْتُ عَلِيًّا يَقُولُ اسْتَغْفَرَ رَجُلٌ لِأَبَوَيْهِ وَهُمَا مُشْرِكَانِ فَقُلْتُ أَتَسْتَغْفِرُ لَهُمَا وَهُمَا مُشْرِكَانِ؟ فَقَالَ اسْتَغْفَرَ إِبْرَاهِيمُ لِأَبِيهِ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَأَنْزَلَ اللَّهُ {وَمَا كَانَ اسْتِغْفَارُ إِبْرَاهِيمَ لِأَبِيهِ إِلَّا عَنْ مَوْعِدَةَ وَعَدَهَا إِيَّاهُ} [التوبة 114] سكت عنه الذهبي في التلخيص – سكت عنه
