Ali ibn Mahziyar, from Ahmad ibn Muhammad, from Hammad, from Hariz, from Zurarah, who said: I (narrator) said to Abu Ja’far عليه السلام and to his son عليه السلام, peace be upon him: “A man has abundant produce from various kinds, or wealth in which there is no single kind in which Zakat becomes obligatory; is there upon him, in all of it, one Zakat?” So the both Imams عليه السلام said: “No, it only becomes obligatory upon him when it is completed, so Zakat becomes obligatory in each kind of it. So if his land brings forth something in the amount in which charity is not obligatory, of various kinds, one Zakat is not obligatory in it.” Zurarah said: “I said to Abu Abdillah عليه السلام, ‘A man has one hundred dirhams, and ninety-nine dirhams, and thirty-nine dinars; does he pay Zakat on them?’” Imam عليه السلام said: “No, there is nothing of Zakat upon him in the dirhams nor in the dinars until he completes forty dinars and two hundred dirhams.” Zurarah said: “And likewise it is in all things.” He (narrator) said: “And I said to Abu Abdillah عليه السلام, peace be upon him: ‘A man had four she-camels (aynuq), thirty-nine sheep, and twenty-nine cows; does he pay Zakat on them?’” Imam عليه السلام said: “He does not pay Zakat on anything from them, because nothing from them has been completed, so Zakat is not obligatory in it.”
