It is narrated from Sayyida Umm Salama (may Allah be pleased with her), the wife of the Prophet (peace and blessings be upon him): In the time of the Messenger of Allah (peace and blessings be upon him), a woman used to have continuous bleeding. Sayyida Umm Salama (may Allah be pleased with her) asked the Messenger of Allah (peace and blessings be upon him) for a ruling regarding her. The Messenger of Allah (peace and blessings be upon him) said: "She should count the number of nights and days in each month that she used to have menstruation before this illness, and leave the prayer for that many days. Then, when those days have passed and the time for prayer comes, she should perform ghusl, place a piece of cotton on her private part, and then perform the prayer."
