Impurities

Q: Is the root of a hair Taahir or Najis?

Q: 

1. I am over conscious about purity and cleanliness. Even though I do my best to wear clean clothes, have clean body and wudu properly so I can offer salah perfectly but I always have doubt about cleanliness. I feel if I touch most things I'll get germs I have to repeat my wudu again. I can't able to do wudu any place anywhere I worry about cleanliness of the place. I have 3 different clothes, I wear 1 set of clothes for toliet, I have 1 set of clothes for going out and I have 1 set of clothes for praying salah.  I worry that if I wear same clothes that I went to toliet with that clothes wouldn't be clean for salah.  I wear sandals at home because I don't want to get germs or dirt from carpet.  I try to avoid touching the door handles so I don't want to get infected with germs. I get thoughts  place where I pray it's not clean enough. If some else prays on my praying mat (carpet) I feel that person made my mat dirty I have to wash it. I waste too much water and long time in wudu and ghusl. I follow the tiny things that are not even seen by eyes to clean them and remove them. After I do wudu I get thoughts like I didn't do wudu properly or I didn't wash 3 times each part of body or I have to repeat wudu again because I was bit careless when doing wudu.  These thoughts I get do I have to accept them or ignore them? I feel if I don't listen to these thoughts my prayer will not be valid?
2. How do keep yourself clean but not trying too hard or listening to shaytaan whispers?
3. I am pretty sure I am suffering waswasas with regards to cleanliness, how can I stop these thoughts?

Q: If the fat from pigs is chemically processed so as to produce two compounds, both different from the original fat, it would be considered as istihalah?

Q: What is istihaalah? Especialy regarding products from pig?

Q: 

1. The splashes of water when washing our private parts in istinja is paak or napaak?
2. The water which wets our feet due to movement of our hand in these situations is pure or impure?
3. Our hand with which we have cleaned those areas if it touches our clothes will the clothes be naapak?
4. Once this happened and where I thought that my clothes has touched my hand, I washed it with water and offered namaz and after some time I began to think that i washed the wrong place. Now I don't know was my namaaz valid?
5. When we wash our hands aftr istinja and the sleeves fall down and it gets wet, do we have to wash our sleeves or not? 

Q: When I went to the bathroom I felt a splash of water or urine on my hand, I don't remember now. I didn't see it that time. I thought I will wash there but when I stood up, my sleeves fell down and I don't know where it was. 

My question is, is my sleeve napaak in both cases if it was impure water or if it was urine or if I don't remember what it was?

Q: At times when I take out a garment to wear from the cupboard, I notice some substance of najaasat on it (not just the trace), what is the condition of the other garments washed together in the washing machine. Many a times I don't even know which were the other garments as it was only noticed after a few days. And if I know which were the other garments, then in this case also,what will be the ruling?

Q: I pray that you can respond to my questions on purity, so that I may feel comfort in knowing what to do in my case. It’s difficult because I don’t have immediate access to people of knowledge. 

I am generally healthy, and don't suffer from incontinence of any sort (Praise Allah), but I frequently get build-up of prostatic fluid through the day that comes out intermittently! Is this normal for men? If I don't clear the passage by milking the penis regularly, then I fear something will eventually come out! For me, how it will come out is by it slowly sliding out of the meatus (only when there is a lot of it usually), not like a droplet sitting at the tip or anything, that only happens rarely.  How I know this, is by feeling the lip of the tip, which sticks out a bit due to movement or when the meatus mouth may become moist due to heat or something making its way out. It’s the side of this lip that I feel which is slightly sticky sometimes. I can look down and think I see nothing, but sometimes this annoying fluid settles beneath the surface and accumulates before fractions of the stuff begin to slide out.  If I just look at the tip, then I see a shiny bit surrounding the opening. Sometimes this shininess is extra shiny, and I don’t know if that is due to this sticky fluid drying on it or if this is due to heat or sweat. If this stuff dries on the tip, generally speaking it is hard to notice.

I also have this terrible habit of inspecting the channel of the penis by putting my finger in it and moving it around to determine if the area is dry, but most of the stuff will definitely come out!  This only makes me certain that I don’t even have to look down there and check; I just assume this stuff has come out, as it seems to be my body’s habit to expel this fluid and it is most likely to be the case.

It's hard for me to check my underwear all the time. This liquid is clear and discreet. It comes out very subtly, so it is hard to detect. If one were to have a flow of this stuff exiting due to say sexual arousement, then because of the amount one would see this great amount on his underwear, if his penis made contact with it.

1. When they say that one has to be certain that something has come out of his penis, then does this mean by certainty we have to clearly see a fluid at
the tip or just emerging in droplet form?

2. Because of this build up, I can't be sure if a fraction of it or even just a tiny droplet has come out when I'm having a shower? I think to myself perhaps something has come out; how can I be sure when in the shower or drying myself off? I worry about it mixing with the water on my body which then gets transferred to my towel. Is my towel pure?

3. Should I do wudu for every prayer to be on the safe side and put some barrier between the penis tip and my underwear between the prayers?

Q: A person has a rash like eczema on his scalp. Sometimes it bleeds a little. At night unconsciously he scratches it and it bleeds sometimes. Now it is very difficult to know where it bled etc, and at fajr time he simply makes wudhu as normal without washing his head. There may be some dry blood on his head. Is performing salaah in this manner permissible or does he have to wash his head completely every morning to make sure there is no blood? Sometimes for Fajr he has to be the imam of a small musallah when the Imam is not there?

Q: I use a raised toliet, when I use water to clean my private part, this water touches dirty water in the toliet then some dirty tiny drops of water bounce back to my legs so basically when I was wash my private part with water this water drop down and mix with dirty water then bounce back to me.  When I look carefully I see very tiny drops of water on my legs. Do I need to wash my legs with clean water? I was told by an Aalim that I don't need to wash my legs because they are only tiny drops of water.  I was told to ignore this but I worry my salah will not be valid.
