The present article scrutinizes an article, written by a Jewish, evaluating some part of shia Imamia beliefs on holy prophet's purity (Esmat) and the number of Infallible ImamsAccording to him, the first shia Imamia textbooks have undergone several changes passing through the time and no sign or trace of shia Imamia belief can be found in these textbooks now.Referring to a book written on first Imamia commentaries, by recoursing to two traditions adapted from Qhomi and Ayashi's commentaries - the first one is about Prophet's meraj and the later is on inferential meaning of Sab' Sanabol (the author calls them 2 strange / unusuall traditions ) - He draws prophet's purity and the number of Imams under question.In first tradition under the verse of 94 of Yonus chapter, it has been talked about God's revelation to holy Prophet in meraj night (revelations regarding Imam Ali' s place,...), according to this, the author linkes this to Prophet's jealousy to Imam Ali and Prophet's doubt in this revelation which lead to Prophet's lack of purity and chastity.In second tradition in which 7 offsprings of Imam Hussein has been mentioned as the meaning of "Model", the author claims this tradition is against whatever contemporary shia believe; this tradition limits the number of infallible Imams to 7 person and claims the 7th of them is Qa'im.
