All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.
In case a woman bleeds for one day or a few days then the bleeding stops and she sees that she is pure, she should perform Ghusl (ritual bath); then start observing Salah and Sawm. She should not wait for any specific number of days after seeing that she is in a state of purity. Since she is pure, Salah is obligatory for her, contrary to the menstruating woman who should not offer Salah or observe Sawm during the days of her menstruation. Once she is pure she should perform Ghusl (ritual bath); start offering Salah and observing Sawm. When the bleeding returns, she should stop performing Salah and Sawm so long as she is menstruating and so on.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
