Impurities

Q: If a small amount of najaasat eg. blood the size of a fingernail falls on the garment, then does the garment need to be changed or can you make it paak by washing it 3 times?

Q: It was raining outside, the sole of my shoes were wet, they touched the top part of my other shoe. The shoes are made of absorbent cotton material. I understand that doubt cannot uplift certainty. But I know that I must have stepped on some kind of najis some where so I think the top part of my shoe became impure, but even if I did there was no trace of it. Also before I stepped on my other shoe I walked for a bit on wet ground, would that have cleaned up the sole of my shoe? I suffer from waswasas as well.

Q: I washed my clothes in the washing machine, one item of clothing, a raincoat which is made from waterproof material came out dripping a bit, but the rest of the clothes were wet but not dripping. Are my clothes clean still?

Q: If someone consumes alcohol and then drinks water or tea and after that drinks water from bottle is that water from bottle pure. I have drunk that water now am I impure is my mouth impure please help? If that water touches my hair will I be impure?

Q: If a dog licks your shoes does the shoe become impure. If you wear it or if the shoe touches you will you become impure? Also after someone rinses their mouth after drinking alcohol, will his mouth be pure?

Q: Someone wears slippers with pigskin soles. If he now takes off the slippers and walks on a carpet, does the carpet becomes impure? The person was wearing socks with slippers that were not wet, but as you know the socks get kind of humid/ from feet heat when wearing/walking. Does such dampness (without actual wetness) transfer the impurity or must it be real wet?

Q: A person who wears shoes with pig leather lining. If his socks become moist due to sweating are the socks impure?

Q: I recently without knowledge used a hand sanitizer that was alcohol based. Are these sanitizer halaal or haraam? If haraam, what should I do after I had used it?

Q:

1. If after consuming alcohol a person drinks a soft drink and then drinks water from the bottle, can we render the water pure to consume.

2. If a family member is alcoholic how can a person keep pure for prayers as far as utensils and house is concerned. Does he have to keep cleaning?

Q: I was having a shower and was washing my backside from faeces. I used soap to remove the smell. I then smelt to check the tips of my fingers to check if the smell had been washed off and it had. After I had oiled and dried my body I after an hour or so passed my hand over my nose and smelt something like faeces on my palm. I only checked my fingertips when I had cleaned myself, so I am guessing that it had not been washed properly. I am now worried I have made my whole body and clothes impure.
