I want to ask you if I have a wet dream but I am sure that I don’t release semen but madhi comes out so ghusl is fardh on me? During ghusl or wudhu if some dirty water falls on body parts so I have to make ghusl (wudhu) again or use some pure water on that?

(Fatwa: 81/112/L=2/1438)

(1) Yes, in this case ghusl shall be wajib on you provided you remember the dream.

(2) There is no need of doing ghusl again, only the impure place should be washed. However, fresh wudhu shall be required provided the impure water flows out of its place.

Allah knows Best!
