Ibn Ravandi is the most famous theologian of Shia Mu'tazilism in the third century AD. After dissenting of I’tizāl theology, he accept Imamyya theology and criticizing Mu’tazilit theology, he was working on defending and explaining of Imamyya thought. On the other hand, Mu’tazilism were always denying his dissension and making lots of accusations against him that the most famous of them was Ilhad (atheism). This accusation is mainly based on his works that believed-in Mu’tazilism opinions- they are wrote in a atheism way. The main question is whether we can trust the Mu'tazilite’s belief and are his works heretical works? The hypothesis is that this is not impossible that Ibn Ravandi has created these works for criticizing Mu’tazilism, their belief about ‘adl and Towhid, and this negative facing of them makes a good field of the accusations. This is why the Mu'tazilites, in order to destroy Ibn Ravandi, illustrate the works as heretical works. By examining the reports of each of these works, which were remained in Kalamy, Rijali, and Fihristi texts, it seems that most of these works have written by a philosophical approach that is not commensurable with Mu’tazilism organization thinking. On the other hand, in another set of the works, because Ibn Ravandi has mentioned to opponent opinions next to his ideas, they have found a good pretext for the accusation; they clime that Ibn Ravandi tries to cover his heretical ideas by these opponent opinions.
