An elderly man who cannot fast and a poor man who cannot feed others?

Question : May Allah reward you. The questioner says: A man cannot fast because of his advanced age, and he cannot feed others because of his poverty. What is obligatory for him?

Answer : Did you hear this obligation, which is almost impossible? A man cannot fast and he has no money. What does he do? We have a legal principle in the Book of Allah the Exalted. Allah the Exalted said: This man cannot fast, so it is dropped from him. He cannot feed others, what then? It is dropped from him. He owes nothing, and he is not required to make up the fast if Allah enriches him or restores his ability so that he can fast. He owes nothing. The same applies to a poor man: Is zakah obligatory on him? No. If Allah enriches him, is he required to pay zakah for the past? No. Yes.
