Abstract
This article deals with the place of the knowledge in the hierarchy of it, idea, saying and action in the Nabawi Sunnah (the Prophetic living). According to the Nabawi Sunnah, the knowledge is always precedence over the idea, saying and action. And it gets form according to itself. If there is a distorting in this hierarchy, it will bring out an idea of superstition. So it is necessary to make the knowledge to the right manner. Firstly, the knowledge should be true and then the aim of the true knowledge also should be used in a useful way. To show what we discuss in this study, we gave a lot of examples in the Prophetic sayings and actions. As a result of this search, we reached that the formula of the knowledge in Nabawi Sunnah is that the true knowledge is to be sought and it should sent a man to the right thinking, right saying and right actions. Otherwise, it is impossible to keep away from the complexity of the world of knowledge.
