Is it permissible to feed a poor person for each day, in lieu of fasting the many days you missed due to illness?

If one breaks their fast due to an illness that is expected to pass, they must make up for it, as Allah Almighty says: "And whoever is ill or on a journey - then an equal number of other days." The large amount of missed fasts a woman has to make up does not permit her to pay fidyah as long as she is able to fast. Fidyah is only sufficient in cases where there is no hope of being able to fast, such as old age or an incurable illness, as stated in the Fiqh Encyclopedia. Therefore, the woman must make up her missed fasts according to her ability, choosing easier times like winter.
