4- حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ مُحَمَّدِ بْنِ سَمَاعَةَ عَنْ جَعْفَرِ بْنِ سَمَاعَةَ عَنِ الْحَسَنِ بْنِ حُذَيْفَةَ عَنْ جَمِيلٍ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ الْعَبْدُ لا يَرِثُ وَالطَّلِيقُ لا يَرِثُ.
4. Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad ibn Sama‘ah, from Ja‘far ibn Sama‘ah from al-Hassan ibn Hudhayfah from Jamil from al-Fudayf ibn Yasar who has narrated the following: “Abu ‘Abd Allah عليه السلام, has said, ‘A slave does not inherit and a free person does not inherit from a slave.’” (It is because a slave does not own anything.)
