Person who has scabs and open wounds making wudhu
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?
