Aishah, wife of Prophet ﷺ , said: Umm Habibah, daughter of Jahsh, sister-in-law of Messenger of Allah ﷺ and wife of Abdur-Rahman bin Awf, had a flow of blood for seven years. She asked the Messenger of Allah ﷺ about it. The Messenger of Allah ﷺ said: This is not menstruation but only vein; so you should take a bath and pray. Aisha (RA) said: She used to take bath in a wash-tub in the apartment of her sister Zainab daughter of Jahsh ; the redness of (her) blood dominated the water.
