The role of similar names concerning Salem ben Mokram in Najashi and Shiekh Tosi's paradoxical opinions

Abu khadije Salem ben Mokram, whose epithet is Abu Salma, is one of transmitters which his authority among other transmitters has been subjected to question. Because of significant legal traditions (their authority depends on Salem ben Mokram’s reliability) and similar names (which sometimes are taken mistaken with Salem ben Mokram and in turn are resulted in weaken some documents and even Salem himself) one can refer to the importance of the study of this transmitter in order to explain his authority.
In this ongoing debate, on the basis of transmitters’ information and by studying authoritative traditions and similar names we have concluded that in order to resolve above mentioned paradox one can say his weakening is subject to contemplation. Despite the intra contradictions of Sheikh’s claims we can say the “summation” and “preference” of Salem is reliable. Even it can be said Salem is authoritative. The Sheikh has weakened Salem because he has identified Salem ben Mokram and Salem ben Abu Salma, the latter has been weakened in transmitter’s books. As a result, the weakening of Salem ben Mokram by Sheikh Tosi is not reliable. And Najashi’s reliance to him remains without paradox.
