Impurities on the ground

Killing a spider on one's carpet

Q: Spiders don’t have blood in their circulatory system. They have something else called haemolymph. Is this impure because a few weeks ago I squashed a spider on my carpet in my bedroom, so does that mean this carpet is impure? I’ve also walked all over this carpet with wet feet after wudu sometimes.

Cleaning water splashes on the floor after flushing the toilet

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?

Wiping a drop of urine from the toilet seat

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?

Wiping impurity off a flat surface

Q: My little brother got urine on his boots at school (at the bottom and top of shoe) and then walked from school to home in the snow, getting them wet. When he came home, he walked through the living room, spreading the wetness from his shoes all over the house. I did my best to wipe all the wetness off the floor but I don't even know all the places the water from his shoes got. Do I consider my living room to be impure? How can I make it pure again? I will have to mop the living room and the rest of the house, it that ok?

Washing a soiled carpet

Q: I am having trouble learning how to purify a carpet. I honestly feel like I have transferred filth in so many places, it must be likely that my salah are not counting. What is the difference between a thick and thin carpet?

I put water three times on impure cat vomit while drying (not completely) with towels in between. But the carpet is thin enough that some water gets to the bottom if I saturate it with enough water. Did I do this incorrectly and now filth is transferred everywhere since later on peoples feet touched that wet area?
