١- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنِ ابْنِ سِنَانٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ تَرَكَ أَخَاهُ لأمِّهِ لَمْ يَتْرُكْ وَارِثاً غَيْرَهُ قَالَ الْمَالُ لَهُ قُلْتُ فَإِنْ كَانَ مَعَ الأخِ لِلأمِّ جَدٌّ قَالَ يُعْطَى الأخُ لِلأمِّ السُّدُسَ وَيُعْطَى الْجَدُّ الْبَاقِيَ قُلْتُ فَإِنْ كَانَ الأخُ لأبٍ وَجَدٌّ قَالَ الْمَالُ بَيْنَهُمَا سَوَاءً.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from ibn Sinan who has narrated the following: “I once asked abu ‘Abd Allah , about the case of a man who leaves behind his brother from his mother. He (the Imam) said, ‘If he has not left other heirs besides him the legacy belongs to him.’ I then asked about a brother from a mother with a grandfather. He (the Imam) said, ‘One-sixth must be given to the brother from his mother and the rest is given to the grandfather.’ I then asked about a brother from the father and a grandfather. He (the Imam) said, ‘The legacy between them is in equal shares.’”
