Is the yellowish discharge that appears immediately after blood and continues throughout the month, sometimes accompanied by a viscous white fluid, considered part of menstruation according to the Maliki school of thought? And how can the days of the menstrual cycle be determined? What should be done regarding the missed prayers and fasting during the period when this yellowish discharge was not taken into account?

Yellowish discharge is considered menses by the Maliki school, even if it continues throughout the entire month. The woman should act according to her previous habit, observing the duration of her menses, and anything beyond that is considered irregular bleeding (istihada). This is the preferred view within the Maliki madhhab and aligns with the Hanbali madhhab. Thus, according to the Malikis, a woman observes her habitual period before the istihada begins, and anything in excess of that is considered istihada. She then performs ghusl after her menses ceases, and she may fast and pray.
