Impurities

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.

Q: If I get some impurity on my clothes then I don't wash it according Islamic law i.e. the cloth is washed 3 times and squeezed with full strength the last time. Instead  I wash it until I feel it is clean. I find it more easier and better than the Islamic way. Is this kufr? 

Q:

1. I feel that when I am performing istanja, water gets splashed on my feet after touching my private parts. What is the ruling about these splashes?

2. Secondly I want to ask about how to clean slippers? If I am taking a bath and my body is najis, then how do I make sure that my slippers are clean after cleaning my body. I suffer from doubts about the inner side of the slippers that it becomes najis if najis water falls on my feet or slippers.

3. Last question is about washing shoes and other things which cannot be squeezed three times after pouring water on them? How do we make them paak if they happen to get najis??

Q: If I place my paak dry clothes in a bucket which was najis a month ago but is dried now. Can I use those clothes or they become najis as well? Theres no visible najasah in the bucket. It became najis because I touched it with najis hands and put najis clothes a month ago.

Q: I had a pimple on my forehead and later showered and a few hours after the shower, I noticed that the dried pimple had fallen off. Do I assume it fell off in the shower or that it fell of recently? If it fell off during the shower, do I consider it pure? 

Q: I would like to know if, eggs that contain tiny blood clots in them when cracked open haraam for consumption?

Recently I have been having a huge problem with both big, small and tiny blood spots in both the egg yolks and white and most of time it is extremely difficult to see and remove all the blood spots especially if they are a lots small and tiny spots in the egg yolks and sometimes the egg whites. If for example I have to bake a cake it can take at times an hour or more to just clean the eggs. In addition, at times it is impossible and very difficult to remove all the clots.

As a result I have stopped eating eggs and anything that contains eggs because I do not want to consume anything that is not halaal and Tayyab. But I also do not want make what is permissable for consumption haraam.

Do we have remove every tiny blood clot in both the yolks and whites or just the big spots.

Please advice accordingly.
