Alternatively, (to point to a commonly used example from the Quran on this point) since there is no necessary connection between fire and burning, it makes sense that God could say "O Fire! be thou cool, and (a means of) safety for Abraham!" when Nimrod tried to burn Abraham alive. Fire doesn't have the power to burn by itself.
In this view, there is also no such thing as a miracle because whether God follows his own habits or not, everything that happens is willed and created by Allah. The created world doesn't even have the power to sustain its own existence for an instant, so another consequence is that Allah is continually recreating the cosmos from moment to moment, almost like a projector shining successive picture frames on a screen.
But all the above is really a preface. To make a long story short, I mainly wanted to share that a few days ago I ran into some friends (a married couple) who generously gave me a beautiful blue fatima's hand. I had mentioned to them some "evil-eye" issues going on in my life along with my fascination with the khamsa and moments later they offered me one (which they had actually bought for themselves in Cairo). It is hanging on my shelf right now. It is definitely one of the most interesting presents I've gotten in a while. In any case, I wanted to be able to say how pleased I was with the gift, without people accusing me of shirk. I know very well that it has no power to help or harm, but ultimately that's not the point.
