Covering and praying, two Islamic prescriptions ,bring religion into public life and debate in Europe. Praying in Europe where Muslims are in minority becomes a public issue. From the perspective of the liberal discourse on religious freedom and the freedom to exercise one’s faith requires a place for worship. The author selects three different practices of praying that have provoked a public debate to illustrate the specificity of contesting religious practices in a European context. Confrontation with Islam carries also European citizens and countries that were considered to be in the periphery of Europe to the Center. Switzerland, a non-EU member, becomes European, enters into the center of European debates by the Islamic door.
