13. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthman from al-Halabiy who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about how much is paid to Zakat collector. He (the Imam) said, ‘It is whatever the Imam deems proper. There is nothing definite about it.’”
