Impurities on clothing and furniture

Doubts regarding urine drops

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?

Doubts regarding impurity

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.

Doubts regarding discharge

Q: Usually I feel wetness and I use the washroom to check what it is as I have doubts. It's usually the normal female discharge. Sometimes to be sure I touch it to check if I have doubts after that I wear my pants back. Do my pants become impure as I have checked the pants with my hand and then used it to wear them back and then washed my hands? Usually I do that so now have the places where I have sat like the bed and blanket etc become impure as I touched that place and then wore my pants back?
