Ghusl And Going To The Toilet
I mean if during the ghusl we need to relieve ourselves we just go to the toilet and then at the end of the ghusl (carrying on from where we left off) do wudu
after relief, you may carry on your Ghusul by washing the remaining parts. it will make your ghusul complete. but if you see that four essential parts of Wudu (face, hands till elbows, Mashah of head and feet) are not washed after you relieved yourself, no matter you did Wudu before, you need to do Wudu again.
