Tahaarat

Q: Is niyyah for ghusl sunnah?

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". 

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. 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?

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: I have been experiencing a few problems lately. Often when I experience an erection, a few drops of what I believe to be semen. I have never had a wet dream so I don't really know what it should look like. This does not happen everytime but it does occur.

a) Am I considered to be mazoor?

b) If not do I have to have a bath every time that happens?

c) If i am mazoor do i have to have a every time?

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: If someone is in need of ghusal-e-janabat, how much time can he remain without taking a bath? I read that permission is granted just till before fajar begins. If someone does not take a bath for two days, will it affect his home because I heard that angels do not visit the home if there is a napak person.

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: Is it sinful to urinate while standing?
