Consensus of early scholars about the probativity of single source Hadith (Khbare Wahid) and its opposite view in Seyyed Murteza and Sheikh Tusi

The debate between Seyyed Murteza and Sheikh Tusi in Consensus about the probativity of single source Hadith (Khbare Wahid) has become one of the most important challenges between usuli scholars in recent centuries. In addition to this outcome in usul, this discussion is valuable in the historical view of Shia and their method for evaluating tradition (hadithes). After complete evaluation of Seyyed Murteza and Sheikh Tusi’s view, this article studies the efforts of late scholars of Usul for solving this contradiction. I do not accept their solution, so we need a deeper review in their views.
