Women having the habit of time only

Women having the habit of time are of two types:

493.

1. A woman who sees blood in each of the two consecutive months on a given day, and then becomes Pak after a few days. The duration of blood varies in each month. For example, if the blood is seen on the 1st of each month but stops on the 7th in the first month and on the 8th in the second month, her habit of time will be the first of every month.

2. A woman who sees blood in two consecutive months on a given day, for, say 3 or more days and then it stops and thereafter is seen again, but the total number of days does not exceed ten days. However, the number of days during the 2nd month is either more or less than the days in the 1st month.
   For example, if the blood is seen on the 1st day of each of the two consecutive months but the total duration of days is 8 in the 1st month and 9 in the 2nd month, she should treat the 1st of the month to be her habit of time.

494. If a woman who has the habit of time but the duration of her hayz is not constant, sees blood on her habitual time or two or three days earlier, she will treat herself as Haaez, and act according to the details given in rule no. 486.
But if the blood is seen much earlier, so much so that it would not be considered as customary, or if she sees it very late, she will treat herself as Haaez if the blood bears the signs of Hayz. Similarly, she will consider it as Hayz if she is sure that the bleeding will continue for three days, even if the blood bears no semblance of Hayz.
And if she is not sure whether this sort of bleeding will last for three days or not, then as per obligatory precaution, she will do all those acts which are wajib for a Mustahaza, and refrain from all those acts which are forbidden to Haaez.

495. If a woman with the fixed habit of time sees blood on her habitual time for more than 10 days and if she is unable to determine the exact duration of Hayz from its signs, then as a precaution, she will follow the habit of her paternal or maternal relatives, irrespective of whether they are living or dead; provided that:

1. The state of her relative does not differ sharply from her state. She, as a young and active person, cannot compare with the habit of an old lady, or the one nearing menopause.

2. She does not compare herself to a woman in her family whose habit is totally different from the habit of the others in the family.

The above rule also applies to a woman of fixed habit of time who fails to see blood on time, and sees it out of the days of her habit for more than 10 days and is unable to discern from the signs.

496. A woman with fixed habit of time cannot shift her Hayz to any period outside her habitual time. Therefore, if her commencing time is fixed on the first of every month, with a varying duration of five or six days, and then suddenly she sees blood for twelve days, and she is unable to recognise the signs to determine the duration of Hayz, she will take the first day of the month as the beginning and as for the duration, she will resort to the foregoing rule (495).
And if she is aware of her final or middle days of habit, and if the total number of days exceeds ten, she will arrange the duration of Hayz in such a manner that her final or middle days fall within the habitual time.

497. If a woman with a fixed habit of time sees blood for more than ten days, and is unable to determine the nature of blood as explained in rule no. 495, then she will be free to decide upon any number of days which she feels could be her days of Hayz. It is recommended that she fixes seven days, and in so doing she must keep in mind her habit of commencement, as mentioned in the foregoing rules.
