Patience and steadfastness from the work of jihad are in the same position as zakat from the fruit, and it is a barrier. The origin is the Almighty’s saying: And I did not create the jinn and mankind except to worship Him. He did not create them except to worship Him, so they are subject to it. Then He made their deeds, which are in the position of fruit from trees, a share for God, which is sincerity in work, and it is from work. It is a right for the employer, which is what he gets in reward for it, and it is in the same position as zakat, which is required for reward. This is the basis of zakat on retained fruit, according to their differences, and God is the Guide.
