Zakah on a joint farm

A: It is obligatory to pay Zakah on grains such as corn, barley, pearl millets, and the like, if they reach the Nisab (the minimum amount on which Zakah is due) which equals five Wasaq i.e. 60 Sa`s (30, 320 kg) of the Sa` (1 Sa`=3 kg. Approx.) of the Prophet (peace be upon him). The estimated Zakah is one-tenth of the outcome as long as the land is irrigated by rain.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
