متى تطهر المرأة التي يأتيها الدم ثلاث مرات في الشهر بصفات مختلفة، وكيف تحسب قروءها إذا طلقت على القول بأن القرء حيض؟

If a woman experiences prolonged bleeding (istihada), meaning her total bleeding exceeds fifteen days, and she does not observe a period of purity that is less than the minimum duration of purity, then she reverts to her previous menstrual habit before the prolonged bleeding. If she does not have a previous habit, she should differentiate between menstrual blood and prolonged bleeding based on the blood's characteristics: its color, smell, and accompanying pain. If she has neither a habit nor a discernible difference, she should estimate six or seven days of the month for menstruation, perform ghusl (ritual bath) after their completion, and consider any bleeding beyond that to be prolonged bleeding. Her 'iddah (waiting period) does not end until three menstrual cycles have passed in this manner.
