Expiation for those with permanent excuses who did not fast

Question:
The sister Umm Ahmad says: I have a son and a daughter with special needs who did not fast this year. Do we have to pay expiation on their behalf?

Answer:
If they have a barrier that prevents them from fasting, and it is a continuous barrier that is not expected to end, they must feed a poor person on behalf of each of them for every day. For each person, this amounts to forty-five kilograms for the month, which is to be given to the poor. It may be given to one poor person, or to one household of the weak, or distributed among several poor people. The important thing is that it is paid according to the number of days in the month that he is unable to fast, whether in the present or in the future, as he is unable to fast either in its proper time or to make it up. Yes.
