Ruling on a woman whose menstruation begins before sunset in Ramadan

She also has another question. She says: I fasted one day of Ramadan, and there were only five minutes left until the time for breaking the fast when my menstrual period started. Is it obligatory for me to make up the Maghrib prayer after I become pure, or not?
Answer: As long as the period started before the sun set, she does not have to pray Maghrib or any other prayer. The fast is not valid for that day on which menstruation began before the sun set; the fast is invalid, and she must make it up. This is if she knows that it started before the sun set, even if it was only five minutes before. Yes.
