A group of sisters want to know the rulings related to the fasting of pregnant and nursing women, and what’s required of  them in terms of expiation, etc.

Answered by Shaykh Amjad Rasheed

The discussion of a pregnant (or, similarly, nursing) woman’s fast is divided into:
1. the legal ruling regarding her fasting or breaking her fast,
2. what is required of her in terms of making up missed fasts,
3. what is required of her in terms of monetary penalty (Ar. fidya) if she breaks her fast, and
4. the amount of the monetary penalty.

I have the following questions about the fidya that must be paid if a woman does not make up the fasting days she missed during Ramadan before the next Ramadan:

1. What is the fidya that she must pay, if any?
2. Is it additive (i.e., does it accumulate from year to year)?
3. Can she feed all the people on one day at a big feast?
4. What qualifies as an excuse for not making up these days? For example, if one never knew that it was obligatory to make up missed fasts before the next Ramadan despite being raised Muslim, does one still have make them up?
