Question:
Do I have to do Ghusl again if a white substance comes out after doing Ghusl?
Answer:
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
If you walked a considerable amount, slept or urinated prior to having a Ghusl (ritual bath), then you do not have to repeat the Ghusl. However, if you did not do any of the above before performing a Ghusl, then the fluid flowing after the Ghusl will nullify it, hence necessitating a repeat of the Ghusl.[1]
And Allah Ta’ālā Knows Best
