Impurities

Q: I spend a lot of time in the washroom, trying to clean impurities. This is because I worry about impurities like urine touching water which comes on my body. I worry about splashes that come while flushing when they land on the floor. Since the splashes from flushing are impure and there is water on the floor and when impurity mixes with a body of water that is less than a certain length and width (I forgot), the whole water becomes impure so I clean the floor as well and the slippers too because they touch the floor. The splashes from flushing also land on the sink nearby so I wash the sink also. I also have to wash the seat where the same splashes also come. Can I simply use the washroom without washing anything and only see if my body is visibly pure or impure and not worry about coming into contact with water that had come into contact with impurities?

Q: I was wondering if it will be permissible to use antibacterial spray such as detol or zaflora to remove najasah on surfaces like doors, door handles and radiators by spraying and then drying with tissue paper.

I also read in a fatwaa that if the spray causes side effects you cannot use it. The sprays I have say they cause eye irritation. Does this mean I can't use it. Can you please respond as I need to know cause it will cause me alot of difficulty cleaning the radiators without spraying them and having to use a wet piece of tissue then a dry one. I also feel if I use a wet cloth I will just spread najasah everywhere.

Q: I travel for work and sometimes my agent takes me around in his vehicle. There are times when his vehicle has some dog hair on the seats and on the floor. By me sitting on the seat, some of the hair may come onto my clothes which I try and remove. Can I read salaah or are my clothes napaak? 

Q: There was 1 drop of urine on my toilet seat and I first dried the seat then poured water from the jug carefully over the seat, while pouring the jug of water over the seat, some water leaked off the seat to the sides and down to the floor. Was this water that leaked najis? And also someone stepped on that water and walked across the house. Is the carpet in the house najis?

Q: I was putting my wet clothes into the dryer, the bottom of my pants touched the floor, I then put it into the dryer... Was it napaak? Did I need to rewash it? If yes, are all the clothes that got dried with it also dirty?

Q:

1. When doing masah in wudhu, if we do it in a rough way and some hair comes out and appears on our hand, are their roots impure?

2. While removing pubic and armpit hair, are the roots of those hairs which have come off impure and will it make our razor impure?

Q: A child urinated on a carpet. The urine dried up without anyone cleaning it. If water falls onto the same place, will that water be na-paak?

Q: I would like to know if ambergris is pure. I've heard that it is either the vomit or faeces of a sperm whale. In light of the Shafi and Hanafi madhab, would a perfume containing ambergris be ritually impure?

Q: If a woman's water breaks during pregnancy, is that water pure or impure. If this water fell on a carpet then how should it be purified?

Q: I once saw some white residue on my washed pants. Our clothes washed in the washing machine never have detergent residue. I don't know why my pants had that. The problem is I didn't know which other clothes were washed with the pants. Are all the clothes impure? Should I repeat any salah?
