If the Zakah collector falsely increases, in his estimate, the amount of the crops in order to increase the farmer's subvention
If the farmer knew this, he should fear Allah (Exalted be He) and should only take what he deserves. This is because the money which he does not deserve to take is unlawful. If he did not know about this until after the Zakah collector left, he should inform the authorities about the reality of his crops and have them reevaluated correctly along with the amount of Zakah which is due. He only has to reevaluate the Zakah for his crops. If he did not know, then he should accept the estimation of the Zakah collector.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
