Is a woman required to repeat ghusl, prayer, and fasting if she sees light brown discharge after performing ghusl following menstruation, given that she had seen dryness before performing ghusl?

If a woman sees a yellowish or brownish discharge (kudra) after purification and it is not within her usual menstrual period, it is not considered menstruation. However, if it occurs within her usual period, she must perform ghusl (definition) again after its cessation. If she does not do so, she is obligated to perform ghusl once she learns of the ruling, and her prayers before that are not valid. As for her fasting, it is valid because ghusl is not a condition for its validity. It is more prudent to repeat the prayers performed before ghusl because they were performed without valid ritual purification.
