Auf, remained mustahada for seven years, and she, therefore, asked for the verdict of Shari'ah from the Messenger of Allah (ﷺ) about it The Messenger of Allah (ﷺ) said: This is not menstruation, but (blood from) a vein: so bathe yourself and offer prayer. 'A'isha said: She took a bath in the wash-tub placed in the apartment of her sister Zainab b. Jahsh, till the redness of the blood came over the water. Ibn Shihab said: I narrated it to Abu Bakr b. 'Abd al-Rahman b. al-Harith b. Hisham about it who observed: May Allah have mercy on Hinda! would that she listened to this verdict. By Lord, she wept for not offering prayer.
