Zakah on grains

A: As for the first case, Zakah is due on the seller, while in the second one there is no Zakah at the time of selling. Lastly, there is no due Zakah unless there are some grains left in the cultivated land, and as such, they should be left until they are ripe and reach the amount of Nisab (the minimum amount on which Zakah is due) and by that time the owner of the land should pay the due Zakah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
