Qumeir (bint Imran, wife of Masruq) said: I asked Sayyida Aisha (may Allah be pleased with her) about a woman experiencing istihada (non-menstrual bleeding), so she replied: She should wait (i.e., refrain from prayer) for the same number of days during which she used to leave prayer (during her regular menstruation), and when the day of purity comes on which she would become pure, she should perform ghusl (ritual bath), then perform wudu (ablution) for every prayer and offer the prayer.
