A woman with a habit of time who experiences bleeding for more than ten days and cannot determine it according to what was said in Ruling 479 can choose any number of days from three to ten that she feels is appropriate for the duration of her ḥayḍ; and it is better that she considers it to be seven days, if she feels it appropriate for herself. Of course, the number of days that she considers to be ḥayḍ must be in accordance with the time of her habit, as mentioned in the previous ruling.
