It is narrated from Hazrat Humaid bin Abdur Rahman that Hazrat Abdur Rahman bin Abd al-Qari was appointed as (supervisor) over the treasury along with Hazrat Abdullah bin Arqam during the time of Hazrat Umar Farooq. When stipends were distributed from the treasury, Hazrat Umar would gather the merchants' goods, then calculate the cash and credit, and then collect zakat from every present and absent person.
