Ghusal

Q: Is niyyah for ghusl sunnah?

Q: If someone is in need of ghusal-e-janabat, how much time can he remain without taking a bath? I read that permission is granted just till before fajar begins. If someone does not take a bath for two days, will it affect his home because I heard that angels do not visit the home if there is a napak person.

Q: If I had a wet dream and after I wake up I didn't feel any wetness but after few minutes some thing comes out then I have to do ghusl?

Q: If I am talking sexy with my wife on phone and some liquid come from penis then gusal is farz or not?

Q:

1. Is there any karaahat or prohibition in urinating in the shower drain before ghusal or if need be during ghusal and restarting wudhu?

2. Does it cause wahm?

3. What about saliva mixing with impurities from janaabat etc?

Q: I had a metal filling put in whilst in a state of janaba and I am now concerned whether my ghusl will be valid once performed? As the metal fillings have covered my teeth while I was junub.

Q: How many days my body will be "napak" if I smoke cigarettes?

Q: If a person made ghusal and thereafter notices a small bit of nail polish on their nails, will they have to repeat the entire ghusal?

Q: In a case where one was not aware that the earrings have to be removed for ghusal (so that water reaches that area), what should she now do about her past salaah etc?

Q: How should one ensure that water has reached the inner part of the ears during ghusal? Is it sufficient for one to make khilaal of the ears?
