Impurities

Q: Is the dust on the soles of shoes pure or impure? When they are washed, they leave traces of mud on the floor, is it paak after drying and napaak when wet? 

Q: Most of my body is paralyzed. I have a caregiver to assist me for my basic needs. Most mornings when the caregiver arrives around 8:30 or later upon checking, we realised that I have passed stool. Some mornings I do not pass. After eating or being awake for some time I sometimes make more stool.

1. If I do not get a smell is it fine for me to continue with eating and other work or should I rather check?

2. Can I do exercises and drink hot water before checking and changing to try to ensure that I just need to change once for the morning?

3. Some mornings I am not well or very tired and find it difficult to sleep after waking up to change. Can I continue sleeping after the caregiver comes or should I break my sleep and check to see if I need to change?

Q: I was away on holiday and some of my clothes got napaak, once the clothes were dry I packed it in a plastic bag and then in my luggage. When I arrived home and unpacked my bag I noticed that most of my clothes were damp, the outside of the plastic bag didn't however seem to be wet (but I can't be 100% sure as it isn't easy to tell). I am not sure what happened at the airline that may have caused the clothes to get damp. My question is whether this makes my bags napaak and everything else that was in it

Q:

1. If we wash napaak cloths in a bucket, will the bucket get napaak? Do all the cloths which we wash afterwards will be napaak?

2. How to make a the bucket paak. I usually pour water inside and outside of bucket using hand shower three times. Is emptying it out after every refill is necessary? 

Q: Could you please let me know if it's permissible to only remove a period stain from a bedsheet with the help of wet tissues before completely washing it in the washing machine or getting it washed from a laundry shop? Will it make the washing machine and other clothes in it najis? It's extremely difficult to wash a king size bedsheet by hand.

Q: With regards to an impurity that cannot be seen, is it sufficient that the impure object (e.g. cloth, fabric) is washed and dryed once, or must it be washed and dried three times?

Q: If urine on the floor is wiped with a wet cloth two times, but the traces of water and some dust is still there, will the floor be considered paak after drying?

Q: The hanafi madthab believe that liquid filth the size of the palms of ones hands is excusable during salah. I was wondering what evidence is there that liquid filth this size is excusable?

Q: I read that the sweat of a kaafir is impure. In the Uk there are lots of shopping centres where the cashiers are non Muslims. If we go to the cashier with our food or clothes and they touch it to scan it are we not allowed to wear those clothes and eat that food?

Q: My question is regarding concrete floor and impurity. I know for a fact that some dry impurity fell on the concrete, so I wiped it once with a dry piece of tissue (and should have left it there). But for some reason I had poured water on it and it went underneath the basin of the bathroom. If I tried my best to soak up the water with tissue, would it be considered clean. Keeping in mind I poured water on it once. I was in a hurry because others needed to use the w/c.
