Did she miss prayers because she was late in performing ghusl after her menstruation stopped? And is it true that if her habit is six days, she suffices with that and prays from the seventh day, and if the bleeding stops, she waits a day and a half? And is yellowness (ṣufrah) considered purity (ṭahārah)?

The maximum duration of menstruation is fifteen days, and any blood a woman sees during this period is considered menses. If a woman experiences purity (cessation of bleeding) during her regular period, she must perform ghusl (ritual bathing) and pray, and the intermittent purity is considered valid. Yellowish and brownish discharges are considered menses during the customary period and when they are connected to blood. A woman recognizes purity by dryness or by the white discharge (al-Qassah al-Bayda’). If a woman sees blood, she must stop praying and abstain from whatever a menstruating woman abstains from. If she sees purity, she must perform ghusl and pray. If she performs ghusl and prays, and then sees blood again within a period that could be menstruation, she reverts to being in a state of menstruation. Yellowish and brownish discharges are menses during the customary period, but they are not menses if they occur outside the customary period and are not connected to blood.
