Ruling 475

If a woman with a habit of time and duration experiences bleeding on the days of her habit for three days or more, and the number of days are more or less than the days of her habit, and if after her bleeding stops she experiences bleeding again on the same number of days as her habit, then in such a case, there are a few scenarios to consider:

1. The total number of days of the two bleedings plus the number of days when her bleeding stops in between does not exceed ten. In this case, the two bleedings together are considered to be one ḥayḍ;
2. The number of days that her bleeding stops in between the two bleedings exceeds ten. In this case, each of the two bleedings is considered to be a separate ḥayḍ;
3. The number of days that her bleeding stops in between the two bleedings is less than ten, and the total of the two bleedings plus the days on which her bleeding stops in between is more than ten. In this case, the first bleeding must be considered to be ḥayḍ and the second bleeding istiḥāḍah.
