Q 1: Here in
there are farmers who cultivate peanuts and do not pay Zakah (obligatory charity) on them, although they produce oil. Is Zakah due on them?
Zakah is due on the peanuts when the crop reaches the Nisab (the minimum amount on which Zakah is due) or more. This is due to the general Command that Allah (Exalted be He) gives in the Qur'an:
O you who believe! Spend of the good things which you have (legally) earned, and of that which We have produced from the earth for you
The amount of Zakah is 5% of the production if it is irrigated by machinery and 10% if it is naturally irrigated with no cost incurred, e.g. By rain or rivers like other kinds of crops.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
