484. Women in the state of Îayà are of six types:
1. A woman with the habit of time and duration: a woman who observes the blood of Îayà at a particular time (of the month) in two consecutive months, and the duration of her days of Îayà is the same in both months, such as a woman who observes blood from the first day of a month to the seventh day in two consecutive months.
2. A woman with the habit of time: a woman who observes the blood of Îayà at a particular time in two consecutive months, but the duration of her days of Îayà is not the same in both months, such as a woman who observes blood on the first day of the month in two consecutive months, but is purified from it on the seventh day in the first month and the eighth day in the second month.
3. A woman with the habit of duration: a woman whose duration of her days of Îayà is the same in two consecutive months. However, the blood is observed at different times (in the month), such as a woman who observes blood from the fifth day to the tenth day in the first month, and the seventh day to the twelfth day in the second month.
To claim that a habit can be formed by observing blood twice for the same duration in one month is problematic, such as a woman who observes blood for five days starting from the first of the month, and ten days later observes blood for another five days.
4. A MuÃtaribah: a woman who has observed blood for a few months without forming a particular habit, or a woman whose habit has been broken and has not formed a new one.
5. A MubtadiÞah: a woman who is observing blood for the first time.
6. A NÁsiyah: A woman who has forgotten her habit.
Each of these categories has a separate set of rules which will be elaborated in the subsequent articles.
