The report also shows that a shift in the color of the blood to some other hue does not negate its being menstrual so long as it occurs within the woman’s prescribed days.

Al-Mughnī states: “If a woman, during the days of her usual cycle, sees yellowish or brownish discharge, it is considered menstruation; but if she sees it after the days of her period have passed, she does not treat it as such.” This was explicitly affirmed by Aḥmad and is likewise the position of al-Thawrī, Mālik, and al-Shāfiʿī, because Umm ʿAṭiyyah said, “We would not count the brownish or yellowish discharge that appeared after the end of the period as anything.” Narrated by al-Bukhārī (326) and Abū Dāwūd (307).
