I have alerted you that rulings follow considerations and lineage, and after the lawgiver has ruled on a matter according to what he ruled on it, we must look at what was considered in it until he was given that ruling, and in this way the knowledgeable is preferred over the ignorant. If this is established, know that puberty is due to age or The growth or maturity of the mind is like the nisab in money. Just as if the nisab is found in money, zakat is due on it. Likewise, an obligation must be imposed on the wise person when he reaches puberty, then after the time of puberty his mind becomes strong due to the passage of time upon him, just as money is increased by trade, so the shortcomings appear. So whoever does not find strength in his mind, God is the one who does it. Absolutely, and that the servant has no effect in the act, he is obliged to pay zakat on the aqasa, and zakat is God’s right to money, so we add to God of his deeds what he should add .
