My wife underwent an operation before the month of Ramadhan. Because of the operation, she was unable to fast (she had one kidney removed and stones removed from the other kidney). Her physician advised her not to fast for the rest of her life. How should she conduct herself regarding the expiation of the missed days of fasting?

Question

If a reliable Muslim physician has advised her that fasting is harmful to her health, then she should not fast. Instead, she should pay the expiation for each day that she does not fast during the month of Ramadhan by feeding one needy person. Each person should be given half a Saa (1 Saa=3 kg. Approx.) of maize, wheat, rice, dates or other such foodstuffs eaten in her country. The expiation should not be paid in cash.
