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:

1. I have persistent acne on my scalp and pimples often pop and pus/blood comes out. If a pimple pops then scabs, are these scabs impure?

2. If I wash my head when it has many scabs on it does the water become impure? If one of these scabs falls off, do I have to purify the area?

3. I also have a persistent toe infection that also drains pus/blood on and off at random times. For nearly all my fardh prayers, the infection spot is bleeding/draining pus. My question is, if my toe is bleeding/draining pus and it's time for prayer, how to I wash the area? I mean if I wash it normally, then the water that runs over it (which will no doubt run over the rest of my toe as well) will be impure, making my entire toe impure. How should I deal with this? In fact, how should one deal with washing bleeding limbs for wudu in general? If one runs water over it, the water becomes impure and everywhere else the water touches becomes impure. Is this impurity disregarded during prayer?
