Its funny, I was having a conversation that went exactly like this just with a slightly different illustration, and sub God/Jesus for Allah. I mean, if it works for you, great... go with it. People all over the world, in every religion, feel the special hand of God/Allah/Christ/Vishnu/etc in their life and that it is the clearest thing in all the world. I see a equal lack of ANY evidence in any of these claims, but it makes all these different people feel good and protected and hopeful about life.
Just please don't disrespect reality and claim there is equal tangible evidence to the doctor treating a diabet patient as their is in the God analogy. Please.
