Three Ramadans have passed and she did not fast, and she is unable to make up the fasts, so what is required of her?

Question:
My brother, may Allah grant us and you success in what He loves and is pleased with, three years have passed and my wife did not fast. She did not fast for three Ramadans. Why? And at that time she was about fifty-two years old and she has bone diseases, and we fed on her behalf, Honorable Shaykh. I do not know if fasting will catch up with her or not. Well, please, Shaykh.

Answer:
She is required to make up the fasts, unless she is unable to make them up, in which case she feeds a poor person for each day. That is, those who cannot fast due to illness or old age, a chronic illness or old age and frailty, feed a poor person for each day, and that suffices in place of fasting. So if your mother is in that condition, feeding suffices for her in place of fasting, praise be to Allah. Yes.
