Like a sheikh who is a guide, he owns the souls of his students and pays zakat on them according to the amount of zakat he was obligated to pay on his own behalf before selling them from God, since he was obligated to pay zakat on his own behalf, so zakat on the souls of his disciples takes the place of that, and if he is one of those who say that the sale is annulled, then he can take back his sale. Until he pays zakat on it, and then he sells it from God, and if he is one of those who say the buyer has the option of enforcing the sale and returning it, then that is up to God if He wishes to accept it and pay zakat on it, and if He wishes, return it to the seller until He pays zakat on it.
