Is it obligatory to abandon prayer throughout the entire 14-day period of menstruation, or is prayer required, and is it obligatory to make up missed prayers when their number is forgotten, especially if signs of purity appeared then the bleeding returned?

The maximum duration for menstruation is fifteen days. If the blood exceeds the usual duration, it is considered menstruation as long as it does not exceed fifteen days. As long as the bleeding stopped for fourteen days, it is menstruation, and she is not required to make up the prayers for that period. If a woman sees purity and then sees blood again within the fifteen-day period, she is considered to be menstruating and should abstain from fasting and praying.
