As for produce that never ripens into dates, grapes that are never dried into raisins, or olives from which no oil is pressed, its zakat is paid out of the sale proceeds; the owner is not required to do anything more than that. In such cases we do not look to see whether the price reaches twenty mithqals or two-hundred dirhams; the only criterion is whether the quantity itself equals five awsaq. If it reaches that measure, a full tithe (one-tenth) is taken from the sale price for all of it that was watered by rainfall, a natural spring, or a river channel, whereas what was irrigated by animal-powered waterwheels or norias is subject to half of one-tenth.

Should the owner find that the actual yield exceeds the assessor’s estimate, he must pay zakat on the excess, for the assessor is only making an educated guess. It has been said that nothing further is required—this is a ruling by way of istihsan—but the first view is preferable, because khars is conjecture while the owner’s subsequent discovery is certain. If, on the other hand, the owner claims that the harvest is less than the estimate, he is not believed and the figure is not reduced, for people cannot be trusted in matters where they stand to lower their obligation.

Wild mountain grapes that grow on land not owned by anyone carry no zakat. If, however, someone gathers them and declares them off-limits to others, zakat becomes due. Likewise, there is no zakat on herbs, green vegetables, or any fruits and the like that are neither stored nor used as staple food.
