Types of Treatment

Pouring urine over a rash

Q: I have a terrible rash on my private part and its very itchy and I loose a lot of sleep because at night it stings and burns. My question is the doctor asked me to pour my urine over my private part it will help heal the rash. Am I allowed to do this because it is umpure and it is najasat unclean so am I allowed to do this and afterwards should I do ghusl?

Christian healers

Q: I'm not sure if you are aware of the recent epidemic of christian healers that's infecting our community like the plague. Christians seem to use the possibility of their mislead leaders healing people, claiming to be annointed by god(though they haven't a clue about who or what god is), as a defence to our statements about the authenticity of Islam and the quran. My question is what should our answer be when they challenge us boasting the capability of their leaders? How is it possible that their leaders do such things? What does the Quran say about this?
