Among Ashari scholars, Fakhr Razi explicitly used the term "Unity of The Divine Acts" and tried to prove this issue through several rational and traditional reasons. This article, by studying the different versions of the "Unity of The Divine Acts" from Fakhre Razi’s viewpoint, assessed his rational reasons in four categories - existential reasons; monotheistic reasons; anti conferment reasons; deterministic reasons - and it was concluded that although the "Unity of The Divine Acts" is a quit discursive issue from his viewpoint, but all his reasons, doesn’t able to prove the correct versions of the "Unity of The Divine Acts"; some reason proves the "Unity of The Divine Acts" means Unity of God's Creativity and Agency (denying partner agency); some, proves the "Unity of The Divine Acts" means direct or indirect agency of God to all actions; some, proves the two former means; some, is just a reason for rejection of the conferment and man dependency in actions; some, proves the deterministic reading of the "Unity of The Divine Acts"; and some also is incomplete so that it can' t afford to prove none of the readings of the "Unity of The Divine Acts".
