Impurities on clothing and furniture

Q:

1) Whilst seated on a high pan toilet and one relieves oneself, does the water, which is often polluted and napaak, that remains and comes from inside of the high pan toilet or commode, happens to splash upon any part of one's body, does Ghusl or wudhu become necessary so that Salaah be performed?

2) When having a Fardh Ghusl, does soap have to be used as a means of removing the dirt and impurity or najaasat which is on one's body, such as after a wet dream, or does merely passing water suffice for the Fardh Ghusl to be done to render one paak and clean to perform Salaah?

B) If merely passing water over the affected or dirty parts of the body is sufficient, is there a specific number of times that water needs to be passed over the dirty parts to render one paak and for the Fardh Ghusl to be completed so that one could perform Salaah?

3) Clothes that have become napaak as a result of wet dream or any najaasat or droppings of urine falling on them, do they become clean as a result of washing them in a washing machine only and thereafter worn and perform Salaah?

4) Is there a specific number of times to wash when making Istinjaa?

5) Does blood which comes onto the topee (headgear) while in Salaah, render the Salaah null and void?

B) if yes, does wudhu and Salaah be repeated or only Salaah?

6) If dried blood is on the topee (headgear) does Salaah read with it be valid?

B) If it was washed and still the marks of blood are visible, will one's Salaah be accepted if one reads Salaah with it? 

Q: I would like to know whether mazi is napaak or not and after the release of mazi is it compulsory for one to make ghusal or change his clothes or can he perform Salaah in that clothes?

Q: I have a question on behalf of some one. My question is that if anyone urinates in the bed without knowing while he is sleeping and shy of washing his bed sheets because what the other people will say, what does he have to do?

Q: I would like to ask about some issues related to manhood. I am a healthy young man, married and father of kids. My issue is that when I'm aroused while sitting, resting or talking with my wife my penis secretes a liquid that's like oil. It is just a drop or two and that happens all the time when we are in good mood and I am at home with my family. I have absolutely no control to stop it. So is this liquid najis? Does my Wudhu and Ghusal break? If I had a wudhu can I pray while that drop on my undergarment is still wet? Can I pray in the same clothes once it is dry?

Q: If a baby throws up on me or my clothes, can I still pray in those clothes or are the clothes napaak? Also, if a baby urinates on me or my clothes, do I or my clothes become napaak? Lastly, if the blood of another person touches me or my clothes, am I or the clothes napaak?

Q: I have a question which always brings doubt to me with regards to ghusal. This happens to me all the time like this morning when I got back home from fajr I went to use the bathroom and on taking out my underpants I found a tiny dot of wetness and small white marks on my underwear. I then urinated and whilst urine emitted I watched to see if anything odd is emitted, I found that a little of white liquid came out as well which was sticky. Is this mani or mazi? I always get confused and then get waswasas. Do I have to make ghusal or do I just put on clean underpants and make wudhu?

Q: If there is napaaki on multiple spots on the wall, can I just use one cloth and wipe them all off the wall generally or would the napaaki spread all over?

Q: Yesterday my husband sat on a bench at the airport which had crumbs on it. I am not sure what the source of the crumbs are and I am now concerned that everywhere he sat thereafter like the car as well as the bags which came into contact with the parts of his clothes that touched the bench have now become napaak. I did check his clothes for traces of crumbs but it was hard to determine what was crumbs or just fluff and dirt and also what was the source of it as he was wearing the clothes the entire day and could have gotten the crumbs and dirt from various sources. Please let me know if I am required to wash everything that his clothes came into contact with thrice to make it paak?

Q: If there is dry najasat-e-ghalizah on a wall, will wiping it down once suffice? Also if clean dry clothes were placed on something that had the dry najasat-e-ghalizah on it, will they become napaak?

Q: If there is napaaki (due to sexual reasons) discharge on multiple places on the same wall, can I use one cloth and wipe it off all at the same time and reweipe with new cloths for the 2 other times or do I have to use cloth in that area wash it and redo 3 times for each of the little places?
