6- مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ عَبْدِ اللهِ بْنِ جَبَلَةَ عَنْ أَبِي الْمَغْرَاءِ عَنْ سَمَاعَةَ عَنْ أَبِي بَصِيرٍ قَالَ سَمِعْتُ رَجُلا يَسْأَلُ أَبَا جَعْفَرٍ أَوْ أَبَا عَبْدِ اللهِ وَأَنَا عِنْدَهُ عَنِ ابْنِ أَخٍ وَجَدٍّ قَالَ يُجْعَلُ الْمَالُ بَيْنَهُمَا نِصْفَيْنِ.
6. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from ‘Abd Allah ibn Jabalah from abu al-Mighra’ from Sama‘ah from abu Basir who has narrated the following: “I once heard a man asking abu Ja‘far or abu ‘Abd Allah, ‘Alayhim al-Salam, when I was with him (the Imam), about the son of a brother and a grandfather. He (the Imam) said, ‘The legacy is made half and half between the two of them.’”
