Chapter on the Rules of Menstruation, Istihadah, and Nifas, and Purification From Them

Through this chain of narration, from Sa’d ibn Abdullah, from Ahmad ibn Muhammad, from Al-Husayn ibn Sa’id, Muhammad ibn Khalid Al-Barqi, and Al-Abbas ibn Ma’ruf, from Safwan ibn Yahya, from Abdur Rahman ibn Al-Hajjaj, who said: I asked Abu Al-Hasan Musa عليه السلام about a woman who had postpartum bleeding for thirty nights or more, then became pure and began praying, but later saw blood or a yellowish discharge. Imam عليه السلام said: "If it is yellowish, she should perform ghusl and pray, and she does not need to refrain from prayer. But if it is blood and not yellowish, she should refrain from prayer for the duration of her usual menstrual cycle, then perform ghusl and resume praying."
