Does the white and odorless vaginal discharge of women nullify ablution?

There is no information narrated from the Prophet Muhammad (saw) about whether the genital discharge of women except that of menstruation, postnatal period, and the abnormal bleeding after menstruation nullify ablution or not. In the sources of Islamic law, it is stated that everything coming from two ways (front and back private parts) nullify ablution of both men and women (Marghinani, al-Hidayah, I,106; Ibn Qudamah, al-Mughni, I, 230; Nawavi, Rawda, II, 102; Kasani, Bada’i, I,24; Ibn Juzayy, al-Qawanin, 89).

According to today’s medical data, it is considered as normal for every healthy woman to produce white and odorless vaginal discharge (rutubat al-farj). This discharge does not come from the womb but from lower parts, and does not mix with any najis (ritually impure) substance. Therefore, the discharge is accepted as clean and it neither nullifies ablution nor prevents someone from establishing prayer when it gets on underwear (Kasani, Bada’i, I, 24; Ibn Abidin, Radd al-Muhtar, I, 305).
