What is the ruling on fasting and making up missed prayers for a girl who has not fully fasted Ramadan since puberty, and has not prayed some of the obligatory prayers, and is asking whether she must fast sixty days for each day she missed, or only one day, and whether she is required to make up the missed prayers?

Regarding the answer: The daughter erred by neglecting ghusl (ritual purification bath), prayer, and fasting after her menstrual period ended. She must make up the days she missed in Ramadan, day for day. If she cannot ascertain the exact number of days, she should make them up until she is reasonably certain that her obligation has been fulfilled. Similarly, she must make up the missed prayers. If she cannot ascertain their exact number, she should make them up until she is reasonably certain that her obligation has been fulfilled. It is permissible to follow the opinion that making up prayers is not obligatory for someone who ignorantly omitted a condition or pillar of prayer, especially if making them up would involve hardship.
