pure, for Umm ʿAṭiyyah (may Allah be pleased with her) said, “We would not consider brownish or yellowish discharge that appeared after the end of purity to be anything.” It was recorded by Abū Dāwūd, and al-Bukhārī transmitted it without the words “after the end of purity.” Among the hadith scholars this narration carries the force of a marfūʿ report, because it is deemed an implicit approval by the Prophet ﷺ. Its implied meaning is that yellowish or brownish discharge seen before the state of purity is menstruation and thus carries all its rulings.

Another point
Q: How does a woman determine that her menstruation has ended?
A: She knows that it has ended when the bleeding stops, and that is indicated by one of two signs:

1. The appearance of the white discharge (al-quṣṣah al-bayḍāʾ): a whitish fluid that follows menstruation, resembling plaster water. It may vary in color according to women’s conditions.
2. Dryness (al-jufūf): she inserts a piece of cloth or a cotton swab into the vaginal passage and withdraws it completely dry—bearing no trace of blood, brownish, or yellowish discharge.

What is required of a woman when her menstruation ends
4. Upon the completion of her menses, a woman must perform the ritual bath (ghusl) by washing her entire body with the intention of attaining purity, for the Prophet ﷺ said, “When your menses begins, leave off the prayer, and when it ends, perform ghusl and then pray.” (1)
