Wudhu

Q: If I find some surma in the corner of my eye and it is like one particle which is smaller than sand, do I have to repeat my wudu? 

Q: I had an operation on my left hand. It is currently bandaged up until just below the elbow. Three fingertips (nails) and the entire thumb is exposed. Please explain to me how to do masah, will the thumb and fingertips have to be washed?

Q:

1. What are fard acts of wudhu? If I want to wash my face and there is some sweat on my face, can I make my hand wet then wipe my face or washing my face is required?

2. Also, if I were to wash my arms or face, normally I wet my hand and touch the tap to close it and wipe my face after touching tap. The tap was wet due to me closing it, so is my wudu valid since my hand had mustamil (used water )?

3. Also when doing masah, if my hand touched my wet face and that water also came in doing masah is my wudu valid? (Here also mustamil water)

4. Is doing wudu in steps compulsory or not?

5. Is it compulsory to complete the wudu before the hands and face get dry?

Q: If whilst brushing the teeth, some blood is seen in the saliva, does this break the wudhu?

Q: If we do wudu with the intention to read Quran, we cannot read salah with it, is it true? What if I perform wudu for being in the state of taharat, can I pray with this wudu or if I intend to pray with this wudu can I read Quran?

Q: Is it mentioned that when we are doing wudu and washing our arms and legs, it should be done in order (i.e. washing hands first till wrist when washing the arm)

Q:

1. I have cavities in my tooth, and when I eat, food gets stuck. When I rinse my mouth or use miswak, it's still stuck. But when I brush my teeth, it easily comes out. Should I brush my teeth before I perform wudhu everytime I eat, or is it okay for the food to be stuck in the cavities?

2. Is it permissible to have dental fillings so that food doesn't get stuck, or is the filling regarded the same as stuck food? If it is permissible, is there any specific type which should be used as a filling? For example, the fillings come in gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

3. Sometimes, the food eaten comes back to mouth unintentionally. When this happens, does wudhu break? What about fast?

Q: If a boil busts somewhere on your body and you only find out after the blood has dried on your clothing. If there is little blood, then do you consider that the the blood would not have flown out of the the wound and that you still have wudhu?

Q: I read that wudhu breaks when fluid comes out of the eye due to eye pain. Is this correct?

Will allerges and itchy/dry eyes fall under this?

Q: Sometimes dry skin of hands (specially near fingers) gets scratched and a little bit of blood appears - which is not more than a dana of rai (رائی دانہ). Does this nullify wuzu?
