ANSWER:

It’s mandatory to make up these fasts and it is like fasting the days of Ramadan. 

Will making up missed fasting days after Eid due to menstruation give same reward as we fast in ramadhan or it will not multiply like rewards multiply and we get normal fasting reward because we are now fasting in normal days?? kindly clarify.

Sheikh, we were told that a person who breaks their fast intentionally either feeds the poor or fasts for 60 consecutive days but what about women on heidh, it would be impossible since every month they get menses

I knw I hv to make up missed fasts of Ramadan first n then fast the 6 days of shawal so it will become a complete month of Ramadan plus 6 days of shwl & we can’t combine them it is clear but can we combine coming days of shawal with missed Ramadan fasts of previous year or the missed days of Ramadan several years back so that we will have double reward n make up the obligation as well.
