Does ear discharge invalidate ablution?
The discharge coming from belly or eye without any pain or ache do not invalidate ablution. However, Hanafis say that ablution is invalidated if the discharge comes out with pain or ache. Because pain constitutes an evident of the existence of a wound. And the fluid coming out of a wound invalidates ablution (Ibn Abidin, Radd al-Muhtar, I, 279). According to Shafi’i school, the ablution is invalidated only with the things coming from front and back private parts of people. The fluids coming from the parts except these two places do not invalidate ablution (Mawardi, al-Hawi, I, 199-200).
