٥ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنِ الْخَشَّابِ عَنْ عَلِيِّ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ أَبِي حَمْزَةَ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) مَمْلُوكٌ فِي يَدِهِ مَالٌ أَ عَلَيْهِ زَكَاةٌ قَالَ لاَ قُلْتُ وَلاَ عَلَى سَيِّدِهِ قَالَ لاَ إِنَّهُ لَمْ يَصِلْ إِلَى سَيِّدِهِ وَلَيْسَ هُوَ لِلْمَمْلُوكِ. 
5. Muhammad ibn Yahya has narrated from Ahmad ibn al-Khashshab from Ali ibn al-Husayn from Muhammad ibn abu Hamzah from ‘Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a slave who has an asset; if there is Zakat on it. He (the Imam) said, ‘No, Zakat is not due on it.’ I then asked, ‘Is his owner required to pay Zakat?’ He (the Imam) said, ‘No, because it (asset) cannot go to his owner and it is not for the slave.’”
