Doubts regarding making ghusal under a shower
Q: I made ghusl. I gargled a couple of times and put water on the nose couple of times then soaped the whole body once including the arm pits and under the private parts also inside the anus will the fard ghusl be done I can’t remember if the bend near the anus got wet and the hairs on the anus got wet I was making ghusl under the shower so will the fard ghusl be done?
A: Don’t pay attention to doubts.
And Allah Ta’ala (الله تعالى) knows best.
