Ruqyah

The problem with my mother is 13 years ago she was operated for left side breast cancer. She had undergone chemo 6 cycles and radiotherapy. Now since past 6 months she complained about the pain in her left side chest and drastic weight loss, the pain was excruciating and after multiple diagnosis and biopsy the Doctor's concluded that her breast cancer has re-occurred and spread to the lungs and part of the liver, there is no other symptom other than the pain, fatigue and weight loss. The allopathic Doctors have said that chemo would aggravate the situation and might make her bed ridden, moreover we are not in the favor of allopathic treatment as we have seen her suffering years ago. Hence we approached ayurvedic doctor and to add to my problem he mixed some medicines in cow's urine and prescribed to take on empty stomach. My mother never misses her prayer, recites quran, reads surah baqrah daily and I give her ruqya water on empty stomach. The fact that she has to drink the urine early morning is killing me though she does not know about anything of this. Kindly help. I don't want to go against Allah and his Rasool (Sallallahu Alayhi Wasallam) and treat my mom. If there is shifa in it I would surely go ahead and give it to my mom. And how can Allah Ta'ala put shifa in such a filth. I have full faith in Allah and hence reluctant to go ahead with the medication.
