'A'isha, the wife of the Apostle (ﷺ) , said: Umm Habiba bin Jahsh who was the spouse of Abdul Rahman bin Auf made a complaint to the Messenger of Allah (ﷺ) about blood (which flows beyond the menstrual period). He said to her: Remain away (from prayer) equal (to the length of time) that your menstruation holds you back. After this, bathe yourself. And she washed herself before every prayer.
