Ibn Sina in his discussion of the reason of existents need to a cause, contrary to theologians, believes that it depends on the possibility of existents and not to their temporal existence. Considering that there is a difference between coming into being and possibility he regards the object of agent's is action the existence of possible thing. Therefore Ibn Sina believes in essential coming into being of the world.
But Hakim Sabzawari with a completely mystical approach has advanced the theory of nominal coming into being.
In his view the existence of contingent beings subsists in the source of divine lordship and thus are not preceded by nothingness and no coming into being has any access to them. On the other hand, extended being as the realm of God's action in the world has different orders such as the order of intellect and then the order of soul, suspended ideas, specific forms, bodily form and prime matter. These orders are preceded by nothingness and later than the order of oneness. Because these names and customs are contingent, in the end they fade away.
