The proof that Knowledge and Power and Will and Life are necessary is the existence of the created things. Because, if any one of these four is denied, why does the created world exist? So, since the created things exist, we know that God is to be described by these qualities. And the reason of the existence of the created things depending on these four is this. He who makes a thing does not make it except when he knows the thing. Then he wills the thing which he would make and, after his willing, he busies himself with making it by his power. Further, it is known that the maker cannot but be living. And Knowledge and Will and Power are called qualities of impression (_sifat at-ta’thir_), for making an impression depends upon them. Because he who wills a thing must have knowledge of it before he aims at it; then, after he has aimed at it, he busies himself with doing it. For example, when there is something in your house and you wish to take it, your knowledge precedes your wish to take it, and after your wish to take it, you take it actually. The connection of these qualities, then, is in a certain order, in the case of an originated being; first comes the knowledge of the thing, then the aiming at it, then the doing. But in the case of God, on the other hand, there is no sequence in His qualities, except in our comprehension; in that, Knowledge comes first, then Will, then Power. But as for the making of an impression externally, there is no sequence in the qualities of God. It is not said that Knowledge comes into actual connection, then Will, then Power; because all that belongs to originated beings. Order is only according to our comprehensions.
