Is it obligatory to make up the fast of the day on which a menstruating woman becomes pure before dawn?

The questioner : This questioner says: If a menstruating woman becomes pure and performs the full ritual bath after the dawn prayer, prays, and completes her fast for that day, is it obligatory for her to make it up?

The Shaykh : If a menstruating woman becomes pure before the appearance of dawn, even by a single minute, and she is certain of her purity, then if it is in Ramadan, she must abstain from food and drink, and her fast for that day is valid, because she fasted while in a state of purity. Even if she does not perform the full ritual bath until after the appearance of dawn, there is no blame on her. Similarly, if a man becomes in a state of major ritual impurity from intercourse or ejaculation, eats the pre-dawn meal, and does not perform the full ritual bath until after the appearance of dawn, his fast is valid. On this occasion, I would like to point out another matter regarding women: if menstruation comes to a woman after she has fasted that day, some women believe that if menstruation comes to her after her fast, before she prays the night prayer, the fast for that day is invalid. This has no basis. In fact, if menstruation comes to her after sunset, even for a moment, her fast is complete and valid. You are not required to fast until you are certain of your purity. If you are not certain, then Allah the Exalted does not burden a soul beyond its capacity.
