The ruling on taking next year's provisions from the crops before paying the zakah

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Some issues regarding zakah have confused us. We have read and heard the following regarding the zakah of crops: When the crop ripens and the grain is cleaned, the zakah is paid on what remains after taking his provisions and those of his family for the coming year. How is that calculated?

Answer:
No, that is a mistake. He does not take for the coming year. It is permissible for him to take his provisions at the time of harvest, meaning he leaves for himself what he eats during the harvest, the planting, and the gathering of the grains or dates. He eats during this period. As for taking sustenance for the year, yes, that is allowed. The zakah becomes obligatory when the crop reaches the stage of ripeness. The obligation of zakah is established in the liability of the owner of the crops or the owner of the trees. However, if they are destroyed before he is able to take them, the obligation is dropped from him. The obligation does not become fixed until he harvests the crop or the palm trees bear fruit. At that point, the obligation is fixed. But if they are destroyed after the onset of ripeness and he was unable to take them, there is no zakah on them, until he stores them in the granary after the harvest and after the cutting, when the payment of zakah becomes obligatory. Yes.
