If a person expiates for an oath and feeds the school students with the hope that ten poor people will be fed from it, is his expiation valid?

Question:
May Allah reward you with good, and may He do you good. If a person expiates for an oath by feeding all the students in the school, hoping that ten poor people will be fed from it, since he does not know them, is his expiation valid or not? Is it necessary to repeat the payment? And if he gives, for example, a bag of rice to a poor family, and that is the expiation for more than one oath, is that action correct? And what is the amount for feeding each poor person? May Allah reward you with good.

Answer:
Ah. Feeding, as Allah the Exalted specified in the Qur'an: The term "the poor" here refers to the needy. If the students whom he fed at the school are poor, then this suffices for him. However, if they are not poor, or if there are both poor and non-poor among them, then if they are not poor, it does not count for him, and he must repeat it. But if there are poor people among them along with those who are not poor, he is obligated to complete the number of poor people and exclude the number of wealthy people among them. The amount of food for each poor person is one and a half kilograms of food, so the expiation for the oath is fifteen kilograms distributed among ten poor individuals, with one and a half kilograms for each. If he gives it to the members of a household that meets the legal number, which is ten or more, it suffices for him. But if they are fewer than ten, he gives the remainder to other poor people, counting the number of household members and giving the rest to other poor people until the ten are completed. Yes.
