Islam explicitly rejects dictatorship and there are no traditions of the Prophet or passages in the Qur'an which clearly give dictators this support.
Bernard LewisYou see Christians and Muslims have one thing in common which they do not share with their other religions as far as I know. They claim to be the fortunate recipient of God's final message to mankind.
Bernard LewisThe Jewish Talmud says that the righteous peoples have an equal place in paradise. The Christians and Muslims agree in rejecting that; they claim that they are the fortunate recipients of God's final message and those who accepted will go to heaven and those who rejected go to hell. So there is a long struggle between the Dar al-Islam and the Dar al-Harb, which in effect was Christendom. This was the perceived enemy. And this has inevitably colored the perception of everything else.
Bernard LewisDuring the first formative centuries of its existence, Christianity was separated from and indeed antagonistic to the state, with which it only later became involved. From the lifetime of its founder, Islam was the state, and the identity of religion and government is indelibly stamped on the memories and awareness of the faithful from their own sacred writings, history, and experience.
Bernard LewisMuslims naturally saw Christendom as their arch rival. One point that is really important to bear in mind, particularly in addressing an American audience, and that is that the Islamic world has a very strong sense of history. In the Muslim world, history is important and their knowledge of history is not always accurate but is very detailed. There is a strong historical sense in the Muslim world, a feeling for the history of Islam from the time of the Prophet until the present day.
