Impurities

Q: Is the mud and water which comes onto the clothes due to heavy rain from the roads paak and will the clothes be paak?

Q:

(A) I had a shower at night. I washed my slippers and feet whilst in the shower.

(B) Then I went out of the house for just over 2 hours wearing the same slippers. When I returned home it is most likely that, by that time, my slippers were dry.

(C) I then got in to the sleeping bag, which I have borrowed from my parents home and which I am using at my house. At the time I went to sleep in the sleeping bag it is most likely that my feet were dry. At the time of sleeping, I thought to myself, when I wake up in the morning I must wash my feet and slippers again as a precautionary measure.

Q: I always have doubts whether I washed my hands after istinja or after washing my child. Will everything I touch become impure?

Q: Sometimes when my daughter swims, she chokes and some of the water comes out of her mouth. Does this make her mouth napaak and if she eats and drinks from dishes thereafter does the dishes also become napaak?

Q: Will clothes with najaast become pure if washed in the washing machine?

Q:

1. Once after urinating some drops came and I touched it with my hand which was less than a dirham. At that time I assumed it to be water and ignored but now I think it was urine and with this same hand I touched the water bottle and I didn't wash it. Since then when I fill the bottle with cool water the outer portion also gets wet and my hand too, so was my hand najis all the time and I might have touched other objects after the hands got wet. I also might have prayed salaah in this way. Will my salah be valid? At that time the impurity was less than a dirham, but due to filling the water as the outer portion also gets wet, will the impurity spread and exceed the size of a dirham and make me najis as well?

2. I get a lot of waswasas about purity and about many other things. Please tell some effective ways to fight these waswasas. I try to ignore but I fail.

Q: What is the diffrence between mani and mazi?

Q: There were very small tiny spots of madhi on my undergarments (very much smaller than the excusable diameter) and when I make istinja the front organ is wet and touched the area but nothing got onto me so as the impurity was of excusable amount can I regard myself as pure even after the wetness from my body touched that area?

Q: There is smell of najasah on a piece of clothing, but no najasah is visible, only smell. (a) Will a salah prayed in this clothing be valid? (b) Does the clothing have to be washed?

Q: I am from India. Mufti sahab please let me know that can I use liquid stiffener (revive) in our clothes for praying namaz?
