ما الفرق الزمني بين العدة بالطهر والعدة بالحيض مع التوضيح بمثال؟

Observing the 'iddah based on purity (Tuhr) is shorter than observing it based on menstruation (Hayd). So, according to this opinion, a woman divorced during her period of purity ends her 'iddah with the onset of the third menstrual period. However, a woman observing 'iddah based on menstruation does not complete her 'iddah until the third menstrual period is fully over. Example: If she was divorced on the last day of her purity, and she menstruates for 7 days and is pure for 15 days; the 'iddah based on purity would be 45 days (one day of purity + two menstrual periods and two periods of purity), whereas the 'iddah based on menstruation would be 7 days longer (the entire third menstrual period).
