For the Muslim, religion traditionally was not only universal but also central in the sense that it constituted the essential basis and focus of iden… - Bernard Lewis

We are accustomed to talking of church and state, and a whole series of pairs of words that go with them lay and ecclesiastical, secular and religious, spiritual and temporal, and so on. These pairs of words simply do not exist in classical Islamic terminology, because the dichotomy that these words express is unknown. They are used in the modern languages. In Arabic, they borrow the terminology used by Christian Arabs. They are fortunate in having a substantial Christian population using Arabic, and they therefore have a good part of the modern terminology at their disposal, in their own language. In Turkish, Persian, Urdu and other languages of Islam, they had to invent new words.

In classical Arabic and in the other classical languages of Islam there are no pairs of terms corresponding to lay and ecclesiastical, spiritual and temporal, secular and religious, because these pairs of words express a Christian dichotomy which has no equivalent in the world of Islam.

The current fascination among Muslims with the history of the Crusades, the vast literature on the subject, both academic and popular, and the repeated inferences drawn from the final extinction of the Crusading principalities throw some light on attitudes in this matter. Islam from its inception is a religion of power, and in the Muslim world view it is right and proper that power should be wielded by Muslims and Muslims alone. Others may receive the tolerance, even the benevolence, of the Muslim state, provided that they clearly recognize Muslim supremacy. That Muslims should rule over non-Muslims is right and normal. That non-Muslims should rule over Muslims is an offense against the laws of God and nature, and this is true whether in Kashmir, Palestine, Lebanon, or Cyprus. Here again, it must be recalled that Islam is not conceived as a religion in the limited Western sense but as a community, a loyalty, and a way of life—and that the Islamic community is still recovering from the traumatic era when Muslim governments and empires were overthrown and Muslim peoples forcibly subjected to alien, infidel rule.
