٨- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ تَرَكَ أَخَاهُ لأبِيهِ وَأُمِّهِ وَجَدَّهُ قَالَ الْمَالُ بَيْنَهُمَا نِصْفَانِ وَلَوْ كَانَا أَخَوَيْنِ أَوْ مِائَةً كَانَ الْجَدُّ مَعَهُمْ كَوَاحِدٍ مِنْهُمْ لِلْجَدِّ مَا يُصِيبُ وَاحِداً مِنَ الإخْوَةِ قَالَ وَإِنْ تَرَكَ أُخْتَهُ فَلِلْجَدِّ سَهْمَانِ وَلِلأخْتِ سَهْمٌ وَإِنْ كَانَتَا أُخْتَيْنِ فَلِلْجَدِّ النِّصْفُ وَلِلأخْتَيْنِ النِّصْفُ قَالَ وَإِنْ تَرَكَ إِخْوَةً وَأَخَوَاتٍ مِنْ أَبٍ وَأُمٍّ كَانَ الْجَدُّ كَوَاحِدٍ مِنَ الإخْوَةِ لِلذَّكَرِ مِثْلُ حَظِّ الأنْثَيَيْنِ.
8. A number of our people have narrated from Sahl ibn Ziyad and Muhammad ibn Yahya from Ahmad ibn Muhammad all from ibn Mahbub from Ali ibn Ri’ab from Zurarah who has narrated the following: “I once asked abu ‘Abd Allah , about the case of a man who leaves behind his brother from his father and mother and his grandfather. He (the Imam) said, ‘The legacy between them is half and half. If they are two brothers or a hundred, the grandfather is with them like one of them. The grandfather with them receives a share like the share of one of the brothers.’ He (the Imam) said, ‘If he leaves behind a sister, then the shares of the grandfather are two shares and the sister receives one share, if the sisters were two, then one-half is for grandfather and one-half for the sisters.’ He (the Imam) said, ‘If he leaves behind brothers and sisters from his mother and father, the grandfather is like one of the brothers and each male receives twice as much as the share of a female.’”
