Salaam. Pardon me for asking this, for it's heading towards women privacy, but I had to ask. How to tell between wadi, mazi, and mani from women? Thank you very much for your time reading and answering this question. Jazakallah khayr.
Manī (ejaculate) is a liquid that sometimes comes out with orgasm and smells like egg whites. The ejaculating of manī necessitates ghusl (showering), whether it happens when asleep or awake. If it is caused to ejaculate on purpose (through masturbation), it invalidates the fast. Madhī (vaginal muscus) is secreted during sexual arousal. It does not require ghusl, but it nullifies ablution and it should be cleaned away. It has no effect on one’s fast.
Some scholars considered manī and madhī impure (najis), but I prefer the opinion that it is pure (the ruling for both is the same for men and women). The purity of manī is the opinion of Imam Aḥmad b. Ḥanbal, and Ibn Taymiyya, while the purity of madhī is the opinion of the two scholars and it is also stated by the great Successor and scholar Saʿīd b. al-Musayyab (it appears we do not have a report on his opinion of the purity of manī). If manī or madhī are on the body or on clothes, there is no need to wash them off for the prayer to be valid. The ruling for them is the same as for mucus from the nose; it’s best to keep the body and clothing clean from it, but it does not invalidate worship.
Wadī is said to be a white discharge (coming from the urethra if I understand correctly) that sometimes happens after urination and is treated the same as urine. It does not necessitate ghusl and has the same rulings as urine.
