Some Wonder About Shi'ism

There are courses on comparative religion. One may read history too and study topics on Islam from the foundation and rivalry of successors to Muhammad resulting in the killing of Hussain (cf if disciples of Jesus had killed one another to become head of the church after Jesus) to the purge in Iran of Zoroastrianism to the hidden imam and especially interesting is Shi'a eschatology comparable to that of pre-tribulationist Christians because it was inspired by the New testament hermeneutics of some, not all Christians of the era.
