mouth

Q:

1. I am excused with regards to wudu due to constant bleeding in my mouth following oral surgery. My mouth is inevitably impure during prayers. I know one is allowed a certain amount of impurity on themselves with which prayer is valid. Does the impurity in my mouth (for which I am excused), count? If I have a bit more impurity (blood) somewhere else on my body, would my salah be valid?

For example, while I was excused after oral surgery, I also had a blood clot in my mucus come out from my nose, and prayed without washing inside my nose (though I checked that there was no more blood in my nose after the clot came out). Is my salah valid?

2. Secondly, I have an infection on my toe from which blood/pus comes out frequently. Usually the amount that comes out is not enough to consider 'flowing'. Blood/pus tends to especially come out when I wash it for wudu.

My question is - given that when I make wudu and blood/pus is coming out, the water that flows over it will inevitably flow over the rest of my toe as well. Am I allowed to pray like that as it is inevitable? Also in general, if blood if flowing from a certain area, and one must pray, and during wudu the water goes over both the area with the blood and other areas, is one allowed to pray after that wudu? Or how does one wash the bleeding area, without spreading impurity? Also, does one have to wash the area that is under the chin, but before the throat, that is between the chin and throat, during wudu?

Q: I had oral surgery yesterday and then had to make fardh ghusl following the end of my menses. Is the ghusl valid even though I have stitches in my mouth? Do I have to repeat the ghusl once the stitches come out?

Q: I have heard that the person who dies while blood comes out of his mouth dies the darjah of a shaheed (martyr). Is this true?

Q: I have seen many people that when their feet touch someone else, they make salaam to him. They touch the person and touch their own hearts and then touch their own mouths. Is there any basis for it and should it be done?

Q: Will the prayer be valid if some miswak fibers unintentionally remained in the mouth and were found after Salaat?

Q: I have read in Bahashti Zewar that vomit that does not equal a mouthful is not regarded as impure in Shariah but if a person vomits small quantities several times and these small quantities together equal a mouthful then it will be regarded as impure. I have also read on the internet (I'm not sure how reliable the following information is) that if a person vomits small quantities several times for the SAME REASON then if together it equals a mouthful, it will be regarded as impure.

1. My question is that if a child vomits up a small quantity of milk while burping after feeding and this happens every time after feeding that a little milk is brought up while burping the child (as usually occurs with babies) then will it be regarded as impure as this is happening for the same reason (burping) and after a very lengthy period, if a person had to add up all these tiny amounts it will eventually add up to a mouthful?

2. Will the same ruling apply to an adult who sometimes when burping after eating, a tiny amount of food is brought up or a small amount of bitter saliva that doesn't equal a mouthful but if after a couple of days it is added up, it will equal a mouthful?
