Egypt after The Islamic conquest

After the Islamic conquest and the defeat of the military leaders from Rome byzantium then their final evacuation from it and the stability of the Arab Muslims on its soil Egypt turned into one of the states of the Islamic caliphate state only by land without the parish and the people it is objective to mention yes the state of Egypt included the land so did it join The parish for the state of Islam as the earth joined did the parish come out of the Roman Byzantine Christian domination to melt into the crucible of the new light religion and we mean: Islam or not? !!! In another saying: How did Egypt rule politically after the stability of the Arab Muslims the new conquerors? Did you 'rule a land and a people' or 'ruled a land only without the parish and the people entering the religion of the rising caliphate state ?! does Egypt start with the Islamic conquest a new stage of freedom and political independence? Or was the Islamic conquest a general stage for the Romans in general in the political dependency or what some call political occupation.
