This study analyzes the concept of "Grace" in the philosophical views of Abu Ali ibn Sina. The accents made in the comments of Eastern peripatetic philosophers are analyzed. Grace is a term that covers the relationship between God, the universe and man. Abu Ali ibn Sina evaluates the concept of grace as an order of goodness originating from God. Through this term, the philosopher focuses on the order of good in the world. Farobi evaluates "Grace" within the framework of the theory of emanation, good-evil and happiness. The philosopher explains the theory of emanation by divine grace. For the world that exists by emanation is also involved in the existence of God and needs the divine will to continue its existence. Therefore, emanation shows that grace is permanent. Moreover, the theory of emanation is the best way to understand the existence of evil. Ibn Rushd considers grace as a special proof of the existence of God. The entire universe was created by the grace and bounty of God. To express this idea, the philosopher uses the term "continuous creation." Therefore, the grace of God to the world is infinite and uninterrupted. According to the philosopher, man is in harmony with the universe. That this harmony indicates the presence of God is evidence of grace.
