Does anyone have any opinions / insight on the following email I was sent?? To provide a solid proof of Shimr, killer of Imam Hussain, being a Shia, we refer to the esteemed and classical Shia scholar, Al-Qummi. Al-Qummi, author of the famous book Mafaatihul-Jinaan, writes in his book: I say, Shimr was in the forces of Ameer al-Mumineen on the Day of Siffin. (Al-Qummi, Safinatun-Najaat, vol.4, p. 492, Chapter Sheen Followed by Meem). Shimr lain was not only shia but also real nephew of umul banin, wife of ali.
