How Should A Person Who Has Many Dasts To Make Up Observe Them?

How should a person who has many dasts to make up observe them?

Those who did not or were not able to observe Ramadan fasting even though being accountable first need to calculate how many days they need to fast and then perform qada for those on the days except the forbidden eid days.

It is appropriate to make intention for each fasting as “to perform qada of the first fast I did not/could not observe.” There are two situations about calculating the total number of missed days:

1. It could be a person who has never fasted since it became a fardh upon him/her. In this regard, lunar months are calculated as one for each year passed since reaching puberty. Lunar months consist of either 29 or 30 days. It would be better as a precaution to count as 30 days.
2. It could be a person who has not observed some of fastings since it became a fardh upon him/her. This person needs to calculate the amount of unobserved fastings as far as possible and perform qada for each day.

Those who have not observed fasting without a valid excuse need to repent and ask Allah for forgiveness in addition to making up for the missed days.
