Cessation of Menstruation During the Customary Period and Its Return

Question:
If the duration of menstruation is eight days, and it stops on the fifth and sixth days of that period, then returns on the seventh and eighth days, does the prayer increase on those days?

Answer:
Yes, if her blood stops during the customary period with a complete cessation, she performs the full ritual bath and prays. If the blood returns, she stops praying. The days of cessation are a period of purity that is interspersed, and it is considered interspersed purity; she performs the full ritual bath and prays, and if the blood returns, she stops praying.
