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?

Doubts with regards to ghusal

Q: I made ghusl and soaped my body twice then gargled and put water on my nose but something tells me I've missed places out although I soaped the whole body twice. Could it be possible for me to miss a place out if I soaped the whole body twice and will fard ghusl be done?

Waswasas with regards to ghusal

Q: I am suffering from so much waswasas. I can't handle it I think I am always napaak. When I perform ghusl after I think I having done it right I don't know if all the hairs have got wet on the body. Could you explain to me a way that you would do it so every hair on the body gets wet so the ghusl counts because I think all my salaahs are not getting counted as well and this is really getting to me. It's on my head 24 hours a day I keep having a shower like 3/2 times a day because I think every time I do ghusl its not correct. I need your help

Washing the feet in ghusal

Q: Is it O.K to wash the feet while standing upright during wudhu without using hands to make khilaal between each toe, because I am over weight. I just thoughrally wash my feet by spreading my toes fingers while standind, I do that only when I sit at the masjid Wudhu Khana. While at home I make the wudu in a standing position, because of the over weight, it's hard for me to sit in the bath tub to wash my feet using fingers. Please Advise me for this.
