1. Those who have the habit of time and duration.
479. Women who have this habit are three types:
First, a woman who sees blood in two consecutive months at a particular time for a particular duration. For example, she sees blood on the 1st of each month and becomes Pak on the 7th of the month. Her habit of Hayz will be from first to seventh of every month.
Second, a woman whose blood does not become Pak, but for two consecutive months at certain several days, for example, from 1st to the 8th of each month, the blood that she sees has the signs of Hayz, or in other words, it is thick and warm and black and it is discharged with pressure and irritation, and other bloods which she sees, have the signs of Istihaza and her first habit is from 1st to 8th of each month.
Third, a woman who sees blood in each of the two consecutive months at a particular time and after 3 or more days she may be Pak for one or more days and the blood is seen again; but the total number of days during which the blood is seen as well as those during which she remains Pak does not exceed 10 days; and in each month the total number of days during which blood is seen, and the intervening days during which she is Pak must be same. In such a case the habit of the woman will be counted according to the days during which blood is seen, not including the intervening days during which she remained Pak. It is not, however, necessary that the intervening days during which she remains Pak should be identical in each month. For example, if in the 1st month blood is seen for 3 days from the 1st to the 3rd of the month and then she remains Pak for 3 days whereas in the 2nd month the blood comes for 3 days and then it stops coming for 3 days and is seen again for 3 days and the total number of days during which the blood is seen is nine; then this woman will be classified as having a fixed habit of nine days
480. If a woman who has a fixed habit of time, irrespective of whether she has a fixed habit of duration or not, sees blood on time or a day or two earlier that blood will be Hayz, even if it does not bear the signs of Hayz. Therefore, she will act according to the rules applied to a Haaez. And if it transpires that it was not Hayz, for example, if she becomes Pak before three days, then she should give Qadha for the acts of Ibadaat, which she has left out
481. If a woman having the habit of time and duration sees blood during all days of her fixed habit plus a few days before and after, and if the total number of days does not exceed 10, all of it is Hayz. And if it exceeds 10 days, then only the blood seen during the days of habit is Hayz and the rest will be Istihaza, and she should give Qadha of the acts of worship which she did not perform during the days before and after her habit. And if she sees blood on all the days of her habit as well as a few days earlier, and if the total number of the days does not exceed 10, all of it is Hayz. And if it exceeds ten days, then blood seen during the days of habit will be Hayz, even if it did not have the signs of Hayz; and the blood seen earlier will be classified as Istihaza, even if it had the signs of Hayz. She will offer Qadha for the prayers left out during those earlier days. And if she sees blood during her days of fixed habit plus a few days after her habit, and if the total does not exceed ten days, all of it is Hayz. But if it exceeds ten days, then the blood seen during habitual days will be Hayz, and the rest is Istihaza
482. If a woman, who has the fixed habit of time and
duration, sees blood on some days of her habit and also a few days earlier and if the
total number of days does not exceed 10 she will add the number of days within her
habitual time to the earlier days and complete her fixed duration. Those will be the days
of Hayz, and the rest will be Istihaza.
483. If a woman has a fixed habit of Hayz, and if she sees blood for 3 days or more, and then it stops and is thereafter seen again, and the gap between the two discharges is less than 10 days, and if the total number of days in which blood was seen together with the intermediary period in which it stopped exceeds 10 days (e.g. when blood is seen for 5 days and then stops for 5 days and is again seen on the following 5 days) then it has various rules:
A. If the blood, all or part thereof, seen in the initial days was during the days of her habit and the blood seen later in the second phase after her temporary state of being Pak, did not come during the days of her habit, then she should treat her first blood to be Hayz and the second one as Istihaza.
B. If the blood seen in the initial days is not during the days of her habit but the second blood, all or part thereof was seen in the days of her habit, then she should treat the entire second blood to be Hayz and the first as Istihaza.
C. If she saw the first and the second blood during the days of her habit, and if the first blood did not last for less than 3 days, then that period along with the intervening days when she was Pak will be period of Hayz, provided that the total period covered by them does not exceed 10 days. And a part of first blood that was before habit days and a part of the second blood which is after days of habit, all are Istihaza. For example, if her habit was to see blood on 3rd to 10th of every month, and during any one month the habit changed and she saw blood from 1st to 6th, and then remained Pak for two days. Thereafter, she saw blood again till 15th. The rule will be that the blood seen from 3rd to 10th is Hayz, and from 1st to 3rd and from 10th to 15th is Istihaza.
D. A part of first and second blood is in habit days; but the first one which was in the middle of habit days is less than 3 days, in which case one should refrain from doing all that is Haraam to Haaez during both bloods and the intervening Pak period, as it was explained later, except than obligatory worships which must be performed according to the rules of Mustahaza woman.
484. A woman who has habit of time and duration, if she does not see blood in habit time and in some other days she sees blood equal to number of Hayz days, if this happens after the time of habit, she must consider it Hayz immediately and if it occurs before the time of habit, and signs of Hayz are present, she may consider it as Hayz; but if the sign of Hayz was not there, she must refrain from doing Haraam acts of Haaez for 3 days except than obligatory worships which must be performed according to the rules of Hayz or Istihaza
485. If a woman who has the habit of time and duration sees blood in her habit, but its days are more or less than her habit and after becoming Pak, again she sees blood equal to days of her habit, she must refrain from doing whatever is Haraam to Haaez during both bloods, except than obligatory worships which will be according to the rules of Istihaza
486. If a woman who has fixed habit of time and duration sees blood for more than 10 days, the blood which she sees during the days of her habit is Hayz, even though it may not have the signs of Hayz, and the blood which is seen after the days of her habit is Istihaza, even though it may have the sign of Hayz. For example, if the blood of a woman whose habit is from the 1st to the 7th of the month is seen from the 1st to the 12th of a particular month, the blood which is seen during the first 7 days will be Hayz and that which is seen during the remaining 5 days will be Istihaza.
