The power to fight it itself is within the Quran.. anyhow let everyone blv whatever they want to. Scroll-up I have given plenty of refrences.

The link that you shared with us clearly states that there is no mention in the Quran about the use of surahs as mystical or magical powers. And it is true. It is not the way you speak arabic, not the words it self but the underlying meaning of the surahs that is the real power.
