Does the phrase, "such that if a woman inserts a piece of cotton or the like, it comes out clean with no trace of blood, yellowness, or turbidity," mean that the clean cotton emerging at that very moment indicates purity, or does it require repetition several times over a specific period? And if the cotton emerging clean at that very moment is sufficient to indicate purity, then what is the ruling regarding the past prayers of a woman who mistakenly thought that the bleeding must cease for a long period? And is it true that ritual bathing (ghusl) from menstruation is performed with the intention of removing major ritual impurity only, and by thoroughly wetting the body with water, rinsing the mouth and nose, followed by a separate ablution (wudu') with the intention of removing minor ritual impurity?
