Not making up for the missed days of fast in Ramadan due to menstruation and not knowing their number

Q 6: A woman says that she fasted the month of Ramadan since it has been due on her, but she has not made up for the days she did not fast in her monthly periods. Now she does not know the number of days she missed and asks what she should do.

A: This woman must make up for the days she did not fast from the previous months of Ramadan and feed a needy person an amount of half a Sa` (1 Sa`=3 kg. Approx.) of the staple food of the country for each fasting day she missed as expiation for delaying the making up of these days until another Ramadan came. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
