Tahaarat

Q: What are the rules for masah for feet during wudhu during winter season? Can I do it while wearing woolen socks or do I need to wear leather closed ones?

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: 

A woman who is a mazoor due to vaginal discharge, she can see white discharge in every waqt (time) of salah during her haidh. Will she remain a mazoor after her haidh is over? Or will she have to check again whether she is mazoor or not?

Q: If a woman puts a tissue paper in her vagina and see that the tissue paper is wet (probably due to the moisture found in the lips of vagina), will wudhu break? Is this also a type of vaginal discharge? 

Q: I was about to have a wet dream, but suddenly I woke up and saw no mazi on my clothes and nothing on my private part. After I stretched, I saw a very tiny drop on my private part. Is ghusal compulsory upon me?

Q: Would it affect the validity of wudhu if a person wears kajal (eyeliner) and applies it on top of the eye? 

Q: If the clothes of a mazoor of istihaadha gets dirty unintentionally in salaah, would the salaah have to be repeated?

If so, how should it be done if you are not sure how many salaahs and the dates?

Example, can you estimate 4 zuhrs and make the following intention "O Allah, I am performing the first Zuhr for your pleasure"?

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?
