Is it permissible for a woman to pray, fast, and engage in marital relations after her postpartum bleeding (nifas) has completely stopped for twenty days, even if she occasionally experiences brownish discharge that is not blood?

When a woman in postpartum bleeding (nifas) observes purity, she must perform ghusl (ritual bath) and pray, and she is permitted all that is permissible for ritually pure women. This is because there is no minimum limit for the postpartum period. If she sees yellowish or brownish discharge after achieving purity within the 40-day period, scholars differ on whether it is considered nifas or not.
