Impurities

Q: 

1. I have Running shoes and what happened is that in these western toilets when you flush the water drops pop out and go far out so you should at least stand a meter away because the outside ones do not have a lid. After I had flushed, I saw a drop on the leather portion of my running shoes (its more like a suede and in the inside of the shoe it says made with synthetic leather) so now I just let it dry because I knew it couldn't go through all the way to my shoe because its synthetic suede. I walked around with it for a couple of days. It rained one day and that spot got wet but water did not flow on it. Yesterday it rained again and the thing is there are 4 little holes on the top part of the suede piece the covers the tip of the shoe. They are about 1 centimeter away from where I remember the drop being and they are on the elevated portion of the shoe and the spot where the drop fell is on the lower portion. My question is enough rain fell on my shoe that the whole suede portion was covered. Now does the whole suede portion become najis? Now when I took my shoe off, the part where the holes where, the sock got wet. So is that najis? I have a feeling this is all waswasas. 
2. My second question is with regards to Ghusl. When I do Ghusl I take too long and I know I waste a lot of water. I just want to know certain things with regards to pouring water. When say there is najasat on my thigh, I pour water down my thigh once. Does it become clean and the water that falls off at what point does it become najis. What ends up happening is I wash the front part of my leg from my waist down then the back then the front going back and forth and then I end up wasting close to 5 minutes in that and end up showering for 15 minutes. Before it was 45 minutes. I would like to reduce it to just 5 mins to 7 ​mins max. Please help me.

Q: A cloth which has najaasat on it, is it ok if I just give it for a wash as the servant will wash it with soap or I have to wash it 3 times first?

Q: Is necessory to do gussal (bath) after awkening from sleep if you find mazi and you definately know that it is mazi. Sometimes I dream of sexual intercourse and when I wake up I find drops of mazi on my exit place of my private part and garments and I definately know that it is mazi (colourless fluid) will I have to do gussl?

Q: When I get up in the morning, I see some little spots on my underwear. I am unable to decide if these are the spots of mani or any other liquid.

But I can give some detail about I experiences related to this problem:

1. I see these spots daily.
2. I feel nothing all night and no wet dream.
3. When I wash my private part, it seems like something oily is applied on the top of it.
4. These spots are white.

​Please tell me if I have to make ghusal daily or just change my underwear after cleaning my private part?

Q: Is spiderweb (cobweb) impure? If one notices some dreads of spiderweb after the has prayed on his face does he need repeat prayer ?

Q: Just before salaah was started by the imaam, i gave a hand to someone. When I smelled my hand I smelt some perfume odour. The person's hand was dry, in this case if the perfume he used did contain alcohol or any other impure ingredients did they transfer to my hand? Is my Salaah valid?

Q: In Europe leather men shoes have leather sole. Mostly this leather is from pork-leather since the sole has to be soft, and being soft is one of characteristic of pork-leather. Now it is that most Muslim buy such shoes and wear them. My question is since these shoes are commonly worn and we do not know exactly who wears them only that is very common, how should our behavior be in the rows of Salaah since people do stand feet to feet. Their socks do they become impure by wearing the shoes as inside the shoe there will some humidity after all, and people do touch each other with their feet i.e with the socks. Since this is a matter of Umoom al Balwaa what is the view of the Ulamaa on this issiue?

Q: If one gets 1 drop of urine on his knee, does the skin become pure by wiping the drop away with a dry tissue and thereafter wiping the skin with a wetted tissue ?

Q: I have a few questions regarding purity. I would appreciate  a response.  I am subject to whispers from Shaitain, and want to understand these matters properly so I can confront this issue.

1. How can one use water to clean themselves after defecating in a modern toilet without getting splashes of water on themselves?  I place toilet paper in the water, but water still splashes onto me.  I often shower the lower part of my body after defecating to be precautious, but I am torn between the feeling that I am wasting water, and doing something most people don't do on the one hand, and the desire to be clean without doubt on the other.
2. To clean a garment that has urine or sperm on it, is it sufficient to wash under a lot of running water a sufficient amount of time, or must  it be washed and wrung three times?
3. When cleaning clothes with najasah on them in a washing machine, what if drops of water from the first cycle splash onto the inside roof of the washing machine, and then those drops of water fall back into the water during a later cycle.  Will these drops of water impurify the clothes?  Is this excessive detail?
4. If someone has wet feet and they walk on carpet or slippers on which there is something impure, is the impurity considered to have transferred onto their feet?{C}

Q: Is the clear discharge of a woman which is odorless najis and does it break the wudhu?
