٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ حَنَانِ بْنِ سَدِيرٍ قَالَ قَالَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) سَأَلَنِي عِيسَى بْنُ مُوسَى عَنِ الْقَيِّمِ لِلْيَتَامَى فِي الإبِلِ وَمَا يَحِلُّ لَهُ مِنْهَا قُلْتُ إِذَا لاطَ حَوْضَهَا وَطَلَبَ ضَالَّتَهَا وَهَنَأَ جَرْبَاهَا فَلَهُ أَنْ يُصِيبَ مِنْ لَبَنِهَا مِنْ غَيْرِ نَهْكٍ بِضَرْعٍ وَلا فَسَادٍ لِنَسْلٍ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isma’il from Hanan ibn Sadir who has said the following: “Abu ‘Abd Allah , has said that ‘Isa ibn Musa asked about guardians of orphans, camels and what is lawful in matters of camels. I said, ‘If he repairs their water tank, finds the lost ones, scratches their itch, he then is entitled to use their milk without excessive use of their udder or harming their young.’”
