A:
Zakah is obligatory on grapes when they reach the Nisab (the minimum amount on which Zakah is due) which is five Wasaqs (1 Wasaq = 60 Sa`s =130,320 kg). Thus, half a tithe of the grapes should be given in Zakah or the value thereof if they are sold. The foregoing applies when the crops are irrigated by machines, waterwheels, and watering pots. However, if the irrigation relies on rain and rivers, and there is no cost; one full tithe is due.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
