How can one make up for missed prayers after the cessation of postpartum bleeding (nifas) and the discharge of discolored fluid for fifty days, and is it permissible to make up prayers after the Fajr and Dhuhr prayers, or is making them up after Asr disliked, taking into consideration suffering from obsessive thoughts regarding prayer?

The brownish discharge connected to blood during the forty-day post-natal period (arba'in) is considered nifas (post-natal bleeding). What occurs after the forty days is not nifas, unless it coincides with the usual time of menstruation, in which case it is considered hayd (menstruation). The prayers that the woman performed while in a state of purity (tahir) are to be made up. According to the Maliki school, it is permissible to make up two days' worth of prayers with each passing day. The order of making up missed prayers should be observed to avoid disagreement. It is permissible to make them up after the Fajr and Asr prayers according to the majority of scholars.
