What is the ruling on prayers performed on days preceding the certainty of menstrual bleeding, and must the Maghrib prayer, which coincided with the onset of bleeding, be repeated, or the Dhuhr prayer, which coincided with the certainty of menstrual blood?

The general rule for blood seen by a woman during the period when menstruation is possible is that it is menstrual blood. If a woman sees blood during this possible period, she must cease praying. If the blood flow stops for less than a day and a night, it is not considered menstruation by the majority of scholars. However, if it returns and the total duration of the two periods reaches a day and a night, then it is menstrual blood. For one who prayed while menstruating due to a misinterpretation, we hope there is no sin upon her, but she must learn the rulings of menstruation. There is no need to repeat prayers performed during the menstrual period. If she experiences purity (cessation of bleeding) and then the blood returns before she performs ghusl (ritual bath), she must make up the prayers she performed between the two bleeding periods, because the purity between two bleeding periods is valid purity. As for the prayers she missed due to menstruation during their prescribed times, it is more cautious to make them up.
