As-salaamu 3laikum, Usually when I do ghusl or have a shower without the intention of ghusl some water gets into the private parts. Later on some of this water might come out; would that invalidate wudoo? I don't know how to stop this from happening. Jazaak Allahu khair

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

There are two parts of a woman's vagina: the external part, which is the part that protrudes when she sits down to use the toilet - it is obligatory to wash this during Ghusl and Istinjaa' (i.e. washing one's private parts after answering the call of nature); second, the internal part - if water enters this part of the vagina and then comes out later on, the woman's Wudhoo' (ablution) is invalidated, however, if it does not reach the internal part, the Wudhoo' is not invalidated if it comes out.

For more benefit, please refer to Fatwa 96674.

Allaah knows best.
