A Study on the Teachings of Three Narrators about Imamate, the Signs of Their Credulity and Their Alleged Exaggration

Throughout history, several hadiths narrated from weak sources or  narrators accused of exaggration found their ways into Hadith resources  for Shias, even the most reliable ones. This phenomenon led to some 
adverse consequences for Shias, such as flat denial of implicit religious  teachings conveyed through hadiths and even questioning the veracity of  some hadiths. One of the crucial responsibilties of hadith scholars is to  contemplate on how to encounter with these hadiths and their narrators,  specially the ones directly related to imamate doctorine.  The present study attempts to revisit the intellectual and hadith heritage 
of three narrators accused of exaggration. They are Sahl Biz Zyad,  Mohammad Bin Sanan Zaheri, Mohammad Bin Ali Abu Somaineh. The  current study also adopts a comparative stance towards hadiths narrated 
by these narrators and hadiths that carry the same content but narrated  from reliable sources. The current paper then seeks to show that these two  groups of hadiths transfer the same content, and the reliability of former group remains intact
