Ghusal

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?

Q: After urinating, when rinsing the private area with a hand shower, the pressure of the water is satisfying. Sometimes, I get really aroused, which follows a discharge. Is this counted as masturbation? Do I have to perform ghusl? 

Q: I want to ask a question about husband and wife relationship. If they perform romance, do touching with hands on each others parts, just touch ones parts to the others part, then before next prayer is it necessary to take a shower to be clean or shower is not compulsory?

Q: I was wondering if you can make wudhu in the shower while having a shower (naked) without being in the state of janabah? If so then what are the steps for it?

Q: I had the bad habit of masturbation. After doing this act I never walked 40 steps or urinated. A clear liquid came out, is ghusal nessacary?

Q: For ghusal to be complete, water should reach every part of the body. If a female is not wearing ear rings, how should the water reach inside that part of the skin of the ears? Someone told me that a female should use a pointed thing like a needle,or something and make it wet and put it inside the pierced part. Is this true?

Q: If a male awakens to find he has discharged semen during the night, but without known arousal or a dream, does it neccesitate ghusl?
