502. Mubtadea is a woman who sees blood for the first time. If she sees it for more than ten days and all the blood has common signs then she should refer to the prevailing habit among her relatives and consider her corresponding duration as Hayz and the rest as Istihaza, keeping in view two provisions in rule no. 495. And if even that seems impossible, then she will be free to fix a certain duration as explained in rule no. 497.
503. If a Mubtadea sees blood for more than ten days, some bearing the signs of Hayz and other that of Istihaza, and if the blood with the signs of Hayz is seen for not less than three and not more than ten days, then all that blood is Hayz. But if she sees blood again before the expiry of ten days and even that blood resembles Hayz, for example, if dark blood is seen for five days and yellowish blood is seen for nine days, and dark blood is seen again for five days, then she should treat the first blood as Hayz and the rest as Istihaza, as explained in the case of Mudhtaribah.
