Impurities

Q: Sometimes after passing urine in the toilet I clean myself. I wipe myself with toilet paper but I didn't make sure whether I was completely dry. Now I keep feeling that urine drops have come out but usually when I check it doesn't happen and it's my doubt. While changing clothes I saw some wetness. Now I'm not sure that what that wetness is. It could be me not wiping dry enough as I didn't wipe very dry and could be water. I'm constantly doubting and checking all the time.

Q: Whilst I was urinating, I felt as though a drop may have touched my leg as I thought I felt it. The question I have is that I am unsure if there was urine on my trousers and I assumed they were clean and prayed my Salaah. Was my Salaah valid, and also, if a scenario like this occurred in future where I am unsure, should I assume that my clothes are clean or my clothes are dirty?

Q: If a person has sperm on his underpants and trouser and does not wash it separately but just puts it in the washing machine as I know the washing machine washes three times, does the other clothes become impure?

Q: I need to know if I had a wet dream during the night and in the morning I realise that in between my fingers theres a bit of sperm. I'm not sure if it touched my bedding because I see no sign of it on the bedding of course my hand did move around during the night. What do I do?

Q: If one has doubts about whether there is semen on ones clothes or not, for example, he is wearing a shirt which may have had, but he is unsure, some semen on it, and that shirt touched clean trousers that he was going to wear after doing ghusl, must he then clean the trousers?

Q: I have heard that there is a fluid which comes out of the male private part(not semen) which does not make ghusal necessary. Is it correct? And how can one tell the difference between the two fluids?

Q: A year back something impure like alcohol fell on my slippers when I went to some place. Now I don't remember whether after coming back I washed it or not or later I washed it. I don't remember whether I kept the slipper unwashed or washed in my cupboard. Though after that I have washed it a lot of times but I can't remember whether that time I had washed it and kept it in my cupboard. Now my other shoes were also kept in there with these and I can't seem to remember whether I kept them inside washed or not. Will my other shoes be impure or will the cupboard be impure as the shoes might have touched. I'm feeling very distressed please help.

Q: If someone is in a state of Janabah and when using the toilet, semen falls on the toilet seat, will using the jug to splash water on the toilet seat wash away the semen or should a wet toilet paper be used also to wipe the seat to make sure it's clean?

Q: If someone spills alcohol on shoes and the shoe is leather type material. I have wiped the area with a wet tissue. Will it be clean as the spot still remains on the shoe. If someone will wear the shoe will he be napaak?
