Treating cancer with the Qur’aan
Question

                Can treating sickness with the Qur’aan heal physical diseases such as cancer as it can heal spiritual diseases such as al-‘ayn (the evil eye) or al-mass (being touched by Shaytaan, i.e., madness), etc? Is there any evidence for that? May Allaah reward you with good.
Praise be to Allah.In the Qur’aan and du’aa’ there may be healing for all 
          ills, by Allaah’s leave. There is a great deal of evidence for that, 
          for example Allaah says (interpretation of the meaning): 
“Say: 
          ‘It is for those who believe, a guide and a healing’”
[Fussilat 41:44]
“And 
          We send down of the Qur’aan that which is a healing and a mercy to those 
          who believe”
[al-Israa’ 17:82]  
          
The Prophet  
          (peace and blessings of Allaah be upon him), when he was suffering from 
          some ailment, would recite into his hands when going to sleep, “Qul 
          Huwa Allaahu Ahad” and al-Mi’wadhatayn 
          [i.e., the last three soorahs of the Qur’aan], three times, each time 
          wiping as much of his body as he could, starting with his head and face 
          and chest. He did this every time he went to sleep, as was reported 
          in the saheeh hadeeth narrated from ‘Aa’ishah (may Allaah be pleased 
          with her).
