A Muslim is permitted to travel as well as to live in a European country as long as he feels free to practice the tenets of his faith as dictated by Islam without being subject to temptation that may lead to moral corruption.
Sheikh `Atiyyah Saqr, former head of Al-Azhar Fatwa Committee, states the following: “Traveling to a non-Muslim country is permissible so long as one is guaranteed freedom to practice his or her religion and tenets of faith.
As for the classification of Islamic and un-Islamic countries, it is mere personal opinion which has no textual authority from the either the Qur’an and Sunnah. Reliable scholars state that the criterion by which a country is called Islamic or is termed as at war with Islam, is the freedom which one enjoys in practicing his or her religion. Even if one lives in a country other than his own, and it is a country which does not adhere to Islam, while he practices his religion freely, he is considered as living in the land of Islam. That is to say he is not obliged to migrate from this country.
Thus, one can travel to any European country provided that you are sure you will enjoy the freedom to practice your religion and tenets of faith.”
