And from him, from Ali ibn Asbat, from Muhammad ibn Ziyad, from Umar ibn Udhaynah, from Zurarah, from Abu Ja’far عليه السلام, peace be upon him, who said: Imam عليه السلام said: “In gold, when it reaches twenty dinars, there is half a dinar due on it, and there is nothing due on what is less than twenty. And in silver, when it reaches two hundred dirhams, there are five dirhams due, and there is nothing due on what is less than two hundred. Then if thirty-nine are added to the two hundred, there is nothing due on it until it reaches forty. And there is nothing due on any fractions until it reaches forty. And likewise the dinars are according to this calculation.”
