Narrated Fatimah daughter of Abu Hubaysh: Urwah ibn az-Zubayr said that Fatimah daughter of Abu Hubaysh narrated to him that she asked the Messenger of Allah ﷺ and complained to him about the flowing of (her) blood. The Messenger of Allah ﷺ said to her: That is only (due to) a vein: look, when your menstruation comes, do not pray; and when your menstruation ends, wash yourself and then offer prayer during the period from one menstruation to another.
