Factors that break wudhu

Q: I have heard that passing wind being in the state of wudhu, breaks wudhu only if the wind has odour or sound. Otherwise wudhu remains valid. Is it true?

Q: If piles come out from the anus without blood, is the wudhu broken?

Q: Is the wudhu accepted if the knee is showing intentionally?

Q: I would like to know if when a person is on dialysis (haemodialysis) where your blood comes out goes into a machine gets filtered an returns to your body. Does this break your wudhu?

Q: I have a graze on my front private part, a bit of skin came off. There is now a build up of water\pus there. The water\pus stayed within the wound and I prayed Asr and Maghrib with the same wudu. I prayed Esha late and when I checked the wound I noticed the water/pus had flowed beyond the wound. I can't be sure if it soaked through my underwear and onto my trousers. I just changed my underwear but wore same trousers to pray. I can't be fully sure it soaked through. I just changed them due to precaution. I have these doubts always.

Q: Will my wudhu break if I wash potty/toilet of my child. Do I need to perform wudhu again?

Q: Could Mufti Saab please advise me on the following masaail regarding the normal (whitish/yellowish) discharge of a woman which she has no control over and which is experienced many times in a day.

1.Will it break her wudhu?

2. Will her wudhu break each time she experiences it even if it occurs 5 times in one salaam time?

3. When will her clothing be regarded as impure?

4. If wudhu does break each time and she was under the impression that the rule of this discharge is the same as the rule of a mazoor will she have to read qadhaas for all the salaahs she may have read in this condition (even when some Ulamaa are of the opinion that this discharge will not break her wudhu)?

5.If Mufti Saab's opinion is that her wudhu will break, how should she maintain radhaa with this fatwah (as it is very difficult to make wudhu so often)?

Q: With regard to the discharge ( clear / white in colour) that a female experiences during her tuhur period:

1. Does she have to make a fresh wudhu for each salaah time if she does not experience discharge at each salaah time. Sometimes even a day will pass with
no discharge.

2. Does the discharge have to be removed at each Salaah?

Q: Does laughing aloud in the prayer break ones wudhu?

Q:

1. I had a scratch on my knee which I thought was almost healed. However, at the end of the day, I noticed many small spots (which I assume was discharge from the wound) on my pants and kurta around the knee area. I do not know when this occurred, but it is likely that some of the discharge occurred while performing sajdah. Do I have to repeat all salaah/tilaawat for that day?
2. If one covers a wound with a bandage, and blood may or may not flow onto the bandage, would it be permissible to perform salaah in that condition, or does one have to be certain that the bleeding has stopped?
3. Referring to (2), can one lead the salaah in that condition?
