Studying and criticism:Considerable viewpoints on backbiting the opponent

One of the considerable questions in the realm of jurisprudence of difference is that whether backbiting the opponents and rejecters is permitted, or prohibited and inadmissible as it is the case about the Shiite which the Imami Jurists called them as the believers. There are two theories among the jurisprudents in this regard. Some of them in the past as well as in our time consider backbiting the opponents as permissible and in the contrast to it, part of them such as Moqaaddas Ardebili and lots of the contemporaneous Foqaha regard it as forbidden and indecent. The correct viewpoint which is considering in this paper is the latter one,therefore, in order to strengthen it and remove its obstacles, theory of permissibility is stated and criticized, and then Ardebili`s approach and the other followers of it is set forth and confirmed by some evidence.
