The Amount a Supervisor of the Properties of Orphans Can Lawfully Use

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 عليه السلام, 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.’”
