Wudhu

Q: I would like to know if ghusl is fardh on a woman if she has a thought and feels a slight discharge, but doesn't check it because on every ocassion it is seen to be normal discharge, and not mani.

I always experience this during istinja and have checked on many ocassions, but have recently stopped checking because I experience a lot of normal discharge and know it can't be mani. I am still doubtful. Am I ritually impure for not checking this time?

Q: I just got 4 of my wisdom teeth removed and my gums are in pain and constantly bleeding. If I rinse my mouth a bunch of blood comes out. So how do I make wudhu, and how do I pray?

Q: Should the dried pus on a pimple be removed during wudhu and ghusal?

Q: If while I'm reading salaah I feel discharge, then I break salaah and check, theres nothing but only when I use tissue I find discharge. Is the wudhu broken? This happens alot and I make wudhu lots of times because I'm not sure if it's broken or not.

Q:

1. If I saw some whitness on my underwear and doubt whether it is impurity or not, does this break my wudhu?

2. What if I have prayed before seeing the whiteness, is my prayer valid?

Q: Is a small amount of waterproof substance excused in wudhu?

Q: In the process of wudhu, there are 4 fardhs; washing the face, the arms, masah of the head and washing the feet. Kindly clear my doubt if washing of the face comprises of gargling the mouth and cleaning the nose.

Q: Are we allowed to talk to others while doing wudhu? 

Q: Does permanent ink affect the validity of wudhu and ghusal?

Q: From birth I have a congenital hip dislocation problem due which I am not able to lift my leg till the height of the wash basin. In most offices, people wash their feet in the wash basins but I can't do that to wash my feet.

Please advice if I can:

1. Do masah on my feet.

2. Wet the complete foot by rolling a wet hand.

3. Use a commode to wash my feet where a Muslim shower is available.
