وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ تَرَكَ أَخَاهُ لِأُمِّهِ وَ لَمْ يَتْرُكْ وَارِثاً غَيْرَهُ فَقَالَ "اَلْمَالُ لَهُ" قُلْتُ فَإِنْ كَانَ مَعَ اَلْأَخِ لِلْأُمِّ جَدٌّ فَقَالَ "يُعْطَى اَلْأَخُ لِلْأُمِّ اَلسُّدُسَ وَ يُعْطَى اَلْجَدُّ اَلْبَاقِيَ".
Al-Hasan ibn Mahbub narrated from Abdullah ibn Sinan who said: I asked Abu Abdullah (a.s) about a man who passed away leaving only his maternal brother as an heir and no other inheritor. Imam (a.s) said: "The entire estate belongs to him." I then asked: "What if there is also a grandfather along with the maternal brother?" Imam (a.s) replied: "The maternal brother is given one-sixth, and the grandfather receives the remainder."
