What is the ruling on someone who missed many days of Ramadan in multiple years? Is she obligated to make up all these days, and is it permissible to feed the poor instead of fasting? Is it permissible to observe voluntary fasts before making up missed ones, such as fasting six days of Shawwal? And is the reward diminished if a new Ramadan begins before the missed fasts are made up?

A Muslim woman must make up for the days she missed in Ramadan (definition) due to childbirth or breastfeeding. She is permitted to make up these days intermittently. The make-up fast must be completed before the next Ramadan. If the excuse persists, the make-up fast is delayed until she is able to perform it. She is not required to feed the poor unless she is completely unable to fast.
