Zakaah on grapes

Zakaah is due on grapes if they reach the nisaab, which is five wasqs (i.e., 300 saa’s), because of the report narrated by al-Bukhaari (1405) and Muslim (979) from Abu Sa’eed al-Khudri (may Allaah be pleased with him), that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “There is no zakaah on anything less than five wasqs.” 

Half of one-tenth of the grapes should be given if they were irrigated at a cost, such as if they were irrigated by machines. But if they were not irrigated at a cost, such as if they were irrigated by rainfall or rivers, then the full one-tenth must be given. 

Al-Nawawi said in al-Majmoo’ (5/440): Zakaah is not due on dates and grapes unless their dry weight reaches the nisaab, which is five wasqs. 

The Scholars of the Standing Committee for Issuing Fatwas said: If the grapes reach the nisaab, which is five wasqs, then zakaah is due on them, so one half of one tenth should be given on grapes. If he sells them he should pay one half of one tenth of their price. This applies if they were irrigated at a cost, such as if they were irrigated by machines or channels or sprinklers. But if they were not irrigated at a cost, such as if they were irrigated by rainfall or rivers, then the full one-tenth must be paid. End quote.
