If a woman with a habit of time and duration experiences bleeding on all the days of her habit and a few days before and after her habit, and if the total number of days does not exceed ten, then the bleeding on all of those days is considered to be ḥayḍ. If the number of days exceeds ten, only the bleeding during her habit is ḥayḍ and the bleeding before and after that is istiḥāḍah, and she must make up the ritual acts of worship that she did not perform before and after her habit.
