The time of feeding on behalf of a sick person who broke his fast in Ramadan and its amount

Question:
Please, Muhammad from al-Hafar al-Batin. Peace be upon you. And upon you be peace. May Allah reward you with good. I have a question. My father has kidney failure, so the doctor said he should not fast. I want to ask about the expiation for the month of Ramadan, which is fasting for thirty days. Okay. And is it permissible for me to give it to a whole family without knowing the exact number of people in the family? I want to give the monetary amount, or I want to buy food for them so I know exactly what the monetary amount is for the expiation, on the basis that I am buying it. Clear. Thank you, Muhammad. His father has kidney failure and did not fast this month, Honorable Shaykh. He asks about the expiation: does he give it to a whole family? And how is this expiation discharged for this father who did not fast because of his kidneys?

Answer:
If he is able to make up the fast, even if it is delayed, then he must make it up if he is able, even if the making up is delayed, and praise be to Allah, the time is spacious. But if he is not able to make up the fast, and his illness is chronic, and he cannot make up the fast, he cannot fast with it, then he must feed one poor person for every day the amount of one and a half kilograms of food. He pays it all at once or in installments. He pays it to several poor people or to one poor person. The important thing is that he feeds for every day the amount of one and a half kilograms of food. Yes.
