Ruling 485. A mubtadiʾah is a woman who experiences bleeding for the first time. If a woman experiences bleeding for more than ten days and all the blood is the same, she must consider the duration of the habit of one of her close relatives to be the number of days of her ḥayḍ and the rest to be istiḥāḍah, provided that she fulfils the two conditions mentioned in Ruling 479. If this is not possible, she must choose a number of days between three and ten and consider that to be the duration of her ḥayḍ, according to the instructions explained in Ruling 481.

Ruling 486. If a mubtadiʾah experiences bleeding for more than ten days, and on some of the days the bleeding has the attributes of ḥayḍ and on others the attributes of istiḥāḍah, then in the event that the bleeding with the attributes of ḥayḍ does not last for less than three days or more than ten, it is all ḥayḍ. However, if she experiences bleeding again before the passing of ten days from the time she experienced bleeding with the attributes of ḥayḍ, and this bleeding also has the attributes of ḥayḍ – for example, the bleeding is black for five days, yellow for nine days, and then it is black again for five days – then, in this case, she must consider the first bleeding to be ḥayḍ and the other two bleedings to be istiḥāḍah, as is the case with a muḍṭaribah.

Ruling 487. If a mubtadiʾah experiences bleeding for more than ten days, and on some of the days the bleeding has the attributes of ḥayḍ and on others the attributes of istiḥāḍah, but the bleeding that has the attributes of ḥayḍ lasts for less than three days or more than ten, then, in this case, she must act according to the instructions mentioned in Ruling 479.
