Impurities

Q: If there is dry impurity (such as pre-ejaculatory fluid) on a solid item (ex. a cellphone) and some wet hands touched it, then will the hands be considered impure? 

Q: If a dog licks you on clothes or body, what is the correct way to clean it?

There is a famous Hadith which mentions that if a dog licks a utensil, the latter should be cleaned 7 times with water and once with soil. Does this apply to just utensils or clothes/body as well?

Q: Is pre-coital fluid considered najaasate ghaleeza or khafeefah?

Will it invalidate salaah?

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?
