The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from Sa’d ibn Abdullah, from Ahmad ibn Muhammad, from Al-Husayn ibn Sa’id, from Al-Nadr, from Ibn Sinan, from Abu Abdullah عليه السلام, who said: Imam عليه السلام said: "The mustahadah (a woman experiencing irregular bleeding) performs ghusl at the time of Dhuhr prayer and then prays Dhuhr and Asr. She performs ghusl again at the time of Maghrib and prays Maghrib and Isha. She then performs ghusl at the time of Fajr and prays Fajr. Her husband may approach her whenever he wishes, except during her days of menstruation, when he must avoid her." Imam عليه السلام further said: "No woman has ever performed this act (the prescribed ghusl and prayers) out of faith and seeking reward except that she was cured of her condition."
