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

This narration can be understood as a recommendation rather than an absolute obligation, despite the use of the term "obligatory." Furthermore, the statement "the ghusl for janabah is obligatory upon her" does not imply that she must also perform a separate ghusl for menstruation. Rather, it is permissible for the ghusl to be intended for both janabah and menstruation simultaneously, as indicated by the earlier narrations. This interpretation is further clarified by the preceding reports, which demonstrate that a single ghusl suffices for both states of impurity.
