Ruling 478 — Purification (Ṭahārah)

If a woman with a habit of time experiences bleeding on the days of her habit or two or three days before her habit, she must act according to the rules mentioned for a ḥāʾiḍ as per the details in Ruling 470. In cases other than these two – for example, when a woman experiences bleeding so much in advance of her habit that it could not be said her habit has moved forward; rather, it would be said that she has experienced bleeding outside the days of her habit; or, she experiences bleeding after the days of her habit – then, in the event that the bleeding has the attributes of ḥayḍ, she must act according to the rules mentioned for a ḥāʾiḍ. Similarly, if it does not have the attributes of ḥayḍ but she knows that the bleeding will continue for three days [she must act according to the rules mentioned for a ḥāʾiḍ]. However, if she does not know whether it will continue for three days, the obligatory precaution is that she must do the things that are obligatory for a mustaḥāḍah and refrain from doing the things that are unlawful for a ḥāʾiḍ.
