Hazrat Muhammad bin Uthman says that I asked Hazrat Salim and Hazrat Qasim about the woman with continuous bleeding (mustahadah). One of them said that she should not pray during the days of menstruation. When the days of menstruation pass, she should perform ghusl and pray. The other said that she should perform ghusl for the period from one Zuhr to the next Zuhr.
