Iranians are a national group, not a religious group and as a result do not have a holy book as such. Currently, most Iranians are Muslims and would have the Qur'an as their holy book. A minority of Iranians today are Baha'i, Jewish, Christian, and the original Iranian Religion: Zoroastrian. Their holy books are: the Kitáb-i-Aqdas, the Torah, the Bible, and the Avestas.
