theillspirit-deactivated2013040 asked: What is the book "jilal ul ayun"? It's by al Majlisi apparently, what is it exactly? I've found excrepts from it where Imam Zaynul Abideen (a) apparently calls Mukhtar (r) a liar???
My understanding is that it is a history of the infallibles.
There are narrations in Shi`i sources which cast aspersions upon Mukhtar (rh). However, there are a couple of possible reasons for this:
1) Sometimes to save the lives of their companions, the Imams would do public tabarra from them, including defaming them (so that they would not appear to be one of their followers). This, in particular, complicates the science of rijal.
2) The traditions are simply inaccurate or false.
But I would need to see the actual tradition itself. Mukhtar is complicated from a historical standpoint, in particular because some people say that he believed not in the Imamate of `Ali ibn al-Husayn but of Muhammad ibn Hanafiyyah. In that regard, all I can tell you is what my own shuyukh have told me, which is that this is patently false and that Mukhtar is a hero and without apparent defect.
