Man’s real challenge in this world is from Satan. Though Satan has no real power, he can lure human beings with fanciful promises to fulfil wishful, imaginary desires and thus manage to make them deviate from the straight path of truth. Satan’s way of misguiding is of two main types: one is superstition and the other is interference in God’s creation. Faith in superstition means expectation of such results from something as have no relation with that thing.
