وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ مَاتَ وَ تَرَكَ أَخَاهُ لِأَبِيهِ وَ أُمِّهِ وَ جَدَّهُ قَالَ "اَلْمَالُ بَيْنَهُمْ أَخَوَيْنِ كَانَا أَوْ مِائَةً فَالْجَدُّ مَعَهُمْ كَوَاحِدٍ مِنْهُمْ لِلْجَدِّ مِثْلُ نَصِيبِ وَاحِدٍ مِنَ اَلْإِخْوَةِ".
Al-Hasan ibn Mahbub narrated from Ali ibn Riʾab from Zurarah, who said: I asked Abu Abdullah (a.s) about a man who died and left behind his full brother (from the same father and mother) and his grandfather. Imam (a.s) said: "The inheritance is divided among them as if they were two brothers or even a hundred. The grandfather is considered as one of them; he receives a share equal to that of one of the brothers."
