ANSWER:

You must ensure that the water reaches all body parts for the Ghusl to be valid, including your private parts whether you had answered the call of nature or not!

QUESTION: I heard washing private part isn’t condition of ghusl, if I don’t pass waste so don’t wash the private part and do ghusl, is it ok? Because then how would the whole body be washed as the whole body needs to be washed for ghusl.
