What should my 70-year-old mother do, who has not made up the Ramadan fasts from her menstrual days for years due to ignorance and fatigue, and does not know the exact number of days, and is now tired and finds making them up difficult; can she feed a poor person for each day, calculated as 7 days per month for those years, or what should she do?

A Muslim woman must make up the days of menstruation she missed during Ramadan (definition). If the mother neglected to learn this religious obligation, she must repent and make up all the missed days, even if she was unaware of the obligation to make them up, because ignorance does not waive it. She must make up what she believes is sufficient to absolve her responsibility. She is not required to pay expiation for delaying the make-up if she was ignorant of the prohibition of delay. Feeding the poor does not suffice for making up the fast as long as she is able to fast, and she can delay it until winter or spread out the days. If the inability to make up the fast is due to an illness from which recovery is hoped, she must wait and then make them up. But if the illness is not hoped to be cured, she must feed a poor person for each day she missed.
