Persia has the honor of creation of a distinct culture centered upon the key word of Allah. This Islamic culture is indeed a completely Iranian phenomenon. Eevery aspect of Persian life accepted this culture and followed it accordingly. You can find this idea of culture focusing on monotheistic notion of world, man, society and life as a whole in every single domain of Persian life. Even the particular Shia reading of Islam came to fore in Iran due to certain considerations that was partially related to the idea of monotheism in its original sense of the word. Iranians sought to indiginize the precious gift that Arabs had given to them. Islam and monotheism centered around the Holy Name of Allah.
