Impurities

Not washing one's hands when waking up

Q: The one who wakes up, his hands are napak? What is the ruling for a person who does not wash his hands and goes to the washroom and touches the taps etc. and after washing his hands does not pour water on the taps and closes the tap. So does his hands, the taps etc. become napak? What about if he touches other things, will that also become napak? 

Rubbing impurity on the ground

Q: I ride scooters and bikes to school. I rolled over non-halal foods/sandwich packages with leftover foods several times when riding on the streets. I live in the U.S. and the sandwiches are subway wraps with wet food oil and sauce and certainly not halal. Hence, the bike tire becomes impure. When I ride it in rainy days, the water splashes from the tire onto my shoes and pants. Since the bike tire is impure the water splash is impure. I have to go back home and wash them every time I pray and it severely impacts my life. However, I heard that walking or rubbing impurity against the ground makes the impure shoe pure. Does this ruling apply to a bike/scooter tires? If so then the bike tire can be regarded as pure as it rubs against the ground so many times?

Paralyzed person delaying in changing after passing stool

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?
