Chapter on Menstruation, Istihada (abnormal bleeding), and Nifas (postpartum bleeding)

Narrated from Abdul-Rahman ibn Abi Najran and Muhammad ibn Salim, from Abdullah ibn Sinan, from Abu Abdillah عليه السلام: I (Narrator) heard Imam عليه السلام say: "A woman in a state of istihadah (prolonged irregular bleeding) who does not attain purity must perform ghusl (ritual purification) at the time of Dhuhr prayer and then pray Dhuhr and Asr. She must then perform ghusl at the time of Maghrib and pray Maghrib and Isha. Finally, she must perform ghusl at Fajr and then pray the Fajr prayer." Imam عليه السلام also said: "There is no harm if her husband has intercourse with her whenever he wishes, except during the days of her menstrual cycle." Imam عليه السلام further said: "No woman has ever followed this process out of sincere devotion without being cured of her condition."
