Fasting while menstruating or during postpartum period
A:
Firstly:
You are obligated
to make up for all the days of fast, during which you were menstruating and were having postpartum bleeding. Fasting while menstruating or during postpartum bleeding was invalid.
Secondly:
You need to do your best to make an approximate counting of the days of fasting which you had not fasted.
Thirdly:
You are not obligated to make up for these missed days consecutively, but you can fast sporadically, in accordance with your ability.
Fourthly:
You must give an expiation, i.e., to feed a needy person for every day of menstruation and postpartum bleeding because of your delay in making up for these days. This feeding for several days can be done all at once, even by giving the entire expiation amount to one needy person.
Fifthly:
If you are too poor to give expiation, then you are not obligated to give it, and fast only will be sufficient for you in this case. (Part No. 9; Page No. 48)
Sixthly:
If you are unable to make up for the missed days of fasting, and you cannot permanently fast Ramadan due to old age or chronic disease and you are able to feed the needy, then feeding the needy will be sufficient for you instead of the fast. In this case, you should give half of a Sa', about (1.5 kg), from the staple food of your country, such as dates, rice, or other similar types of food. However, if you are unable to feed the needy and you cannot fast, then you are not obligated to do any of them, due to Allah's (Glorified and Exalted be He) Saying:
So keep your duty to Allâh and fear Him as much as you can
and His (Glorified be He) Saying:
Allâh burdens not a person beyond his scope.
We ask Allah for success, and may peace and blessings of Allah be upon our Prophet Muhammad, his family and his Companions.
