However, God Almighty tested him with an affliction that He afflicts any of His creation, either to make him happy or to make him miserable according to what enables him to use it. So the affliction that He afflicted him with was that He created in him a power called thought and made this power the servant of another power called the mind and forced the mind with its sovereignty over it. Thought is to take from it what it gives, and He has not given thought any room except in imaginative power, and He, Glory be to Him, has made imaginative power a place.
