Shiavault - a Vault of Shia Islamic Books Background of the Birth of Islam Religion in the Achaemenid Period In Iran, according to available sources, there existed a faith called Mizda'i which professed faith in one god named Ahura-Mizda, a name, having a root which is similar to a Greek word, meaning , great and possessor of wisdom', hence Ahur-Mizda would mean the great god of wisdom and reason.
This faith professed belief in god as the unique creator of the world, and a belief in a number of secondary and tertiary gods, and in angels, in the resurrection which is all very significant, and also in good deeds as something very essential. Thus it is a highly interesting point of note that as a result of such basic religious education in ancient Iran, Islam spread so swiftly eastward.
The Mizda'i religion during subsequent periods became corrupted with superstitions so that a man called Zoroaster appeared to reform the Mizda'i religion. His place of appearance has been a subject of controversy in history.[^28] Of course Zoroaster is not a prophet but a reformer of the Mizda'i code.
As to the appearance of Zoroaster quite odd accounts are related in history about the place and the date of his appearance, though generally historical indications place his appearance about six centuries B.C. simultaneously in regions which had a common origin and similar conditions, namely India and Iran. In Iran Mizda'i faith is an ancient religion, and in India Brahmanism is an ancient faith, but no evidence is available about the date of origin of either of them.
Mizda'i faith was later on corrupted by superstitions, and Zoroaster as the reformer makes his appearance in Iran. In India Brahmanism, too, gets mixed with superstitions, and a man named Buddha appears to reform it. There is a great resemblance between the life of Zoroaster and Buddha in all the phases from the beginning to the end.
In the Semitic regions, too, six centuries later, namely concurrent with the rise of Jesus[^29] Christ (a.s.) the main faith had been the monotheistic religion of Judaism. This religion to faith was spoilt by superstitions, and a man named Jesus rose to fight those superstitions. In this way the life of Jesus Christ (a.s.) resembles those of Zoroaster and Buddha.
I do truly wish that I could have delved in deeper study in the similarity present, especially in the case of Zoroaster and Buddha, as both of them have a fifty percent resemblance with the lire of Jesus.
