Religion v/s Religion

Religion vs. Religion consists of two lectures Ali Shariati gave at the Husayniyah Center in Tehran on August 12 and 13, 1970. In them he puts forth a most remarkable thesis, that throughout history, religion has fought against religion and not a non-religion as we have come to believe. That is, monotheism, the religion of the belief that God is One, that religion brought by Prophet Abraham which is called din alhanif, ‘the rightful religion,’ has continuously, throughout history, had to struggle against the religion of denying that there is One God or believing that there is no God (kufr, disbelief, infidelity, atheism) or against the religion of believing that there are multiple gods (shirk, polytheism, (multiatheism), the latter of which has branched into idolatry.
