Arabic (Original)
وَأَخْبَرَنَا أَبُو سَعِيدٍ أنا أَبُو عَبْدِ اللهِ ثنا مُحَمَّدُ بْنُ نَصْرٍ ثنا إِسْحَاقُ بْنُ إِبْرَاهِيمَ مِنْ كِتَابِهِ أنا عَبْدُ الرَّزَّاقِ أنا ابْنُ جُرَيْجٍ أَخْبَرَنِي عَطَاءٌ أَنَّ عَلِيًّا ؓ كَانَ يَجْعَلُ الْجَدَّ أَبًا فَأَنْكَرَ قَوْلَ عَطَاءٍ ذَلِكَ عَنْ عَلِيٍّ بَعْضُ أَهْلِ الْعِرَاقِ الصَّحِيحُ عَنْ عَلِيٍّ ؓ أَنَّهُ كَانَ يُشْرِكُ بَيْنَ الْجَدِّ وَالْإِخْوَةِ وَلَعَلَّهُ جَعَلَهُ أَبًا فِي حُكْمٍ آخَرَ وَاللهُ أَعْلَمُ
English Translation
Abu Sa'id informed us: Abu Abdullah narrated to us: Muhammad ibn Nasr narrated to us: Ishaq ibn Ibrahim narrated from his written records: Abd al-Razzaq informed us: Ibn Jurayj informed me: Ata told me that Ali (may Allah be pleased with him) used to treat the grandfather as a father. Some scholars from Iraq rejected Ata's attribution of this to Ali. The authentic view from Ali is that he shared inheritance between the grandfather and siblings. Perhaps he treated the grandfather as a father in another ruling. And Allah knows best.
