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. For instance, on the basis of self-styled suppositions, one may believe that someone other than God is the controller of the affairs of the world, while it is a well-established fact that no one enjoys any power save God. Superstition can also take the form of being fully involved in worldly activities and then, by wishful thinking, hoping to achieve success in the Hereafter without having worked hard for it.
