Influence of Arab invasions on the Persian language prose until 5th AH century

Arab invasions of Iran is one of most vital and critical events which had been occurred in the ancient Iran. Arabs invaded to Iran during second caliph era and they conquested the different regions of this area. This invasion was one of the bloodiest attacks which Iran had experienced it and Iranian had lost their supremacy and headership and had enslaved by the Bani Umayyah after having defeated against the Arabs and they had been suffered by their racial discrimination policy. Arab invasions of Iran had significantly influenced on the social, economic and cultural status of Iran and it is normal that defeated poor nation is always affected upon the culture and traditions of predominated nation and the Arab invasion apart from taking into account the religious and ritual characteristics of Islam, had tragic and bad consequences for Iran, especially the racial policy of the Bani Umayyah which called the Iranian as Mawali and there was no place for Iranian in any formal positions. Authors in the current paper found that until 5th AH century, Iranian still thought to revive their previous majestic and glorious era and they hardly resisted against the Arabs and literary works of this era especially until 5th century did not affect by the Arabic language and its words and this has been served as a type of resistance against the Arabic culture and language.
