Tahaarat

Sweat of a kaafir

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?

Cleaning dry impurity from the floor

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.

Preparing food and eating in the the state of janaabat

Q: I had ejaculation last night and don't have ghusal. I have 3 questions:

1. If I wear clean clothes, do they become impure (naapak) if my body has sweat and my clothes become wet as my body is impure (naapak).

2. If I drink or eat something without ghusl will it be haram?

3. If I prepare food and wash my clothes with water in this condition will both of these things become impure if I dont have ghusal?

Doubting whether wetness is mani or discharge when waking up

Q: I got up and noticed wetness but as I was having this kind of discharge most of the time nowadays and before sleeping there was some discharge, so I didn't do fard ghusl and read fajr and recite Quran. But I was feeling like I was sinning as the amount of discharge was not this much before sleeping and on the other hand it was like normal discharge which I was experiencing normally. Now is my salah valid or not?

Method of making tayammum with a small stone

Q: In Tayammum, is it necessary that the whole palm/hand be able to touch the earth? For example, if someone is sick on a hospital bed, if a small pebble was brought to them, and when they strike this pebble, first with the right hand and then with the left hand, a very small part of the palms touches the pebble... would this taymmum be valid? So actually my questions are:

1. Can the hands strike the "earth" separately (first strike with right and then left), or do both have to strike the earth together?

2. Can tayammum be done with "earth" which is so small that the whole surface area of the palm doesn't cover the "earth". 

Washing impure clothing

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? 

Fardh and sunnah acts of wudhu

Q:

1. What are fard acts of wudhu? If I want to wash my face and there is some sweat on my face, can I make my hand wet then wipe my face or washing my face is required?

2. Also, if I were to wash my arms or face, normally I wet my hand and touch the tap to close it and wipe my face after touching tap. The tap was wet due to me closing it, so is my wudu valid since my hand had mustamil (used water )?

3. Also when doing masah, if my hand touched my wet face and that water also came in doing masah is my wudu valid? (Here also mustamil water)

4. Is doing wudu in steps compulsory or not?

5. Is it compulsory to complete the wudu before the hands and face get dry?
