While ghusl if one passes wind or urine by mistake then we should do wudhu again after the ghusl is done but if our body gets partially or completely dry by the time we r doing wudhu after ghusl, then shall we have to repeat our ghusl referring to the fact that our body has to stay wet while the process?

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.

If one’s ablution is invalidated while performing the obligatory Ghusl (ritual bath), then he has to perform ablution again. If he performs ablution again, then he has done what he is obliged to do even if this were a long period after Ghusl.

It is not a condition for the validity of ablution that the whole body remains wet (after Ghusl) nor is this a condition for the validity of washing what remains of one's body in case he/she has not washed it yet.

Allaah Knows best.
