Is a girl who ate and drank during the last days of her Ramadan menstrual cycle, then became pure in the evening, considered to have deliberately broken her fast, knowing that she was unaware of the obligation to fast immediately after the cessation of blood?

A menstruating woman is not obliged to fast, and it is not permissible for her to fast as long as she is menstruating. If she purifies during the day, she is not required to abstain from food and drink. The woman mentioned is not intentionally breaking her fast; she only needs to make up the days she missed because she did not experience purity until the evening. If she had seen dryness before dawn, she should have promptly performed ghusl and fasted without waiting for the white discharge, according to the more preponderant opinion. If she did not do so out of ignorance of the ruling, there is no sin upon her, God willing, because the issue is a matter of scholarly disagreement. Some scholars believe it is obligatory to promptly perform ghusl upon the cessation of bleeding and dryness, while others permit a woman to wait for dryness during her habitual period.
