Making Up Missed Fasts from Years Ago

Fasting during Menstruation out of Ignorance

If a person did not fast at all in Ramadaan, does he have to make up 30 days or the number of days that were in the month?

She does not remember whether she made up the days that she owed or not

She claims that there is no evidence that a woman who menstruates has to make up missed fasts

If a person breaks his fast on a day when he was making up a missed fast, does he have to fast three days?

It is not permissible for one who has started an obligatory fast to break it without a legitimate shar’i reason

She did not fast for many days because she was unaware of the ruling and does not know how many days they were

Are these people obliged to fast? Are they obliged to make up the fast?

Is it permissible for him to break his fast because his work is difficult?
