Abstract. The discussion of divine power and will is very important in theology, particularly in Islamic theology. Since other issues such as determinism and will are related to these attributes. Mulla Sadra opinions can be useful in this regard, therefore, in this article the historical trend (power and will) from the perspective of some pre-Islam philosophers including seven sages and post-Islam peripatetic and illuminati philosophers have been investigated and then the opinions of Mulla Sadra about these attributes and influence of Khawjeh Nasir have been explored.  Khawjeh Nasir believed that the God is autonomous and his intellect is the cause of the intellection of the first effect and since both essence and intellection are unified so both of them will be unified. Thus, existence of the first effect is intellection of God. Mulla Sadra has discuses his beliefs about God that is interpreted as the knowledge of God; however, this knowledge is other than the peripatetic knowledge of God since Sadra believes in knowledge on everything in the being step and the power and will are referred to this knowledge. Hence he has stated in “Asfar”: all beings are attributed to God since they are originated from him and when they are assigned to his knowledge and he has knowledge on them and his knowledge is due to his will.
