What is the judgment on the bleeding of a woman who had a miscarriage?
According to Hanafis and Hanbalis, the blood coming from a woman who had a miscarriage of a baby, whose organs such as hands, feet, or fingers became apparent, is postnatal blood. On the other hand, the blood seen after a miscarriage, which occurs before baby’s organs such as hands and feet become apparent, is istihadha (excuse) blood (See. Marghinani, al-Hidayah, I, 226; Ibn Qudamah, al-Mughni, I, 431). According to Shafi’i and Maliki schools, miscarriage is a cause of being in the postnatal period in both cases (Ramli, Nihayat al-muhtaj, I, 212; Dasuqi, Hashiyah, I, 174-175).
It should be taken into account that these judgments were given by jurisprudential schools in the times when it was possible to decide if the thing coming from womb was a fetus or not only by its organs such as hand or foot (See. Kasani, Bada’i, I, 43). Today as it is possible to identify if it is a fetus or not regardless of its phase in the womb, it will be more appropriate to act accordingly. In this respect, whether its organs are apparent or not, as it is known that the miscarried thing is a fetus, the blood seen after miscarriage should be accepted as postnatal blood.
