Impurities

Q: Is it permissible to use paintbrushes made of horse hair?

Q: In my pregnancy I've been getting clear or yellow discharge very rugularly.

So sometimes if I'm out and I have slightly more than a Dirham size then I just sprinkle water over it and try to scrape it a bit but it's always wet, not dry. So sometimes I can't wash and change my underwear when I'm out.

Does sprinkling water over suffice?

It worries me because of my wudhu and salaah and it's validity.

Q: Is colostrum najis. The fluid from the breast’s of a pregnant woman?

Q: If I flush the toilet after passing urine. While washing the areas of my body I have noticed the bidet splashing water inside the toilet and then onto the seat or floor. This water is coming from inside the toilet. The splashes are few. Some splashes I can wash off. But some fall on the ground.

Does this mean I have to thoroughly clean the floor after every use? 

Q: I would like to know my state of cleanliness because I am unsure. Due to my current illness, I have to wear specific sanitary items/nappies for urine leaks. I bought a new type of sanitary nappy and saw that the edges sat tightly around my body. However, at night when I turned, it moved a tiny amount. These nappies have inside cuffs that sit on the groin area for urine to stay inside, and then you have a tight elastic on the edge.

My question is, if the edge moved slightly, does this mean my clothes or hands are affected by the impurity if they get in contact with that area?  

Q: If a najaasat-e-ghaleezah that is thin and flowing falls on the body or clothes, it will be excused if the area on which it falls is equal to or less than a fifty cents coin in extent. If the person performs his salaat without washing it off, his salaat will be valid. But to refrain from washing it and to continue offering his salaats in this way is makruh. If it is more than a fifty cents coin, then it will not be excused. Salaat will not be valid if it is not washed off. Beheshwati Zewar (pg 44).

Does this include mazi?

What is meant by makrooh (disliked or sinful)?

Can I still read quran?

Q: The prayer mat (musalla) that I use has the image of a masjid. When it becomes napak, will it be permissible to wash it in a washing machine?

Q: I have a question regarding impurity and touch screen phones. I would like to know how invisible impurity such as urine traces or other invisible impurity may be removed from a cellphone as it cannot be washed as it would be ruined. Would wiping the dry invisible impurity with a dry cloth remove it from the smooth surface of a phone? Or how about a wet cloth that is wetted with isopropyl alcohol (as this does not harm the phone)?

Q: I have got the scholarship for further studies abroad. I pray fives times a day.

1. The country I am going to, they eat pork and dog meat. This scholarship will be a life changing opportunity for me but I am worried that I need to interact with the local people on a daily basis, like professors and other classmates. Anything haraam I should avoid while interacting with them like hand shake or exchanging things?

2. I need to rent a room. They normally keep dogs as pets in their houses and fridges are also available in the rented houses in which they keep dog meat and pork. Should I use this fridge, stove and how to clean (purify) this place for living here if they kept dog meat in there?

3. I will offer prayer in that room. Explain briefly about the najasat of dogs and their saliva because dogs are everywhere in this country. They are in public places and sitting onbenches that are basically for humans to sit on. 

Q: Do dried impurity make the body impure when one is sweating?
