Ghusal

Q: If a male becomes baaligh by having wet dream and ghusl becomes fardh on him, but he doesn't know that in Shariat you have to perform ghusl after having a wet dream. So he keeps praying with just making wudhu and after 3-4 months of his puberty, he comes to know that ghusl becomes fardh by wet dream. So are all his prayers in these 3-4 months counted or does he have to make qadha?

While offering these prayers again will he make intention of praying qadha prayer or will he make intention of repeating the prayer (I'adah)?

Q: Once, ghusl was fardh on me, and in ghusl, when I had to rinse my mouth, I rinsed it in a normal way and gargled too. But I am quite sure that water didn't reach my inner cheeks inside the mouth. Is ghusl valid?

Q: Is it compulsory for woman to remove her earrings, etc. when taking a ghusl or can she just adjust it front and back so water can go through the holes?

Q: I was having a sleep over at my friends house and while sleeping there I had a wet dream. I couldn't make gusul, so I did a normal wudhu. Is this acceptable?

Q: What should one do when one has done an action (e.g. ghusl or wudhu) and he is 90% or more certain that the act was done but 10 hours later one begins to doubt.

Q:

1. Is using a shower considered to be contrary to the sunnah of a bucket bath?

2. If one has a shower, how should one achieve a sunnat ghusl?

3. Would it be better to use a bucket despite having a shower available?

4. Does the same thing apply regarding wudhu and using a tap vs the mudd utensil?

Q: After one has a shower, is it necessary to then perform wudhu in the normal way for salaat? Or is wudhu deemed to take place when one has a shower? 

Q: I get frequent wet dreams. The problem is that it takes me about 30 mins daily to do ghusl. The main problem in ghusl is washing my feet which can take upto 20 mins because my feet has dirt inside the lines so I rub them with a pedicure stone until they are gone.

I am moving to a hostel for educational purposes and there I will have only few, maximum 5 mins for a bath as there will be a communal bathroom. Plus, the temperature can be 0°c or below too so I can't take a long bath. What do I do as I am becoming depressed due to this thing?

Q: If I have olive oil in my hair and I make wudhu/ghusl afterwards, is my wudhu/ghusl accepted?

Q: I was not able to take out one or two strands of pubic hair during shaving. I still made my ghusal for haidh. Was my ghusal valid?
