Islam has been an official state-recognized religion in Austria since 1912, when its status was legally established by the Austro-Hungarian Empire. However, although the current law requires that officially-recognized religions not contradict Austrian law, the state has never systematically examined the content of Islamic teachings in order to discover whether Islam is compliant.
All that may be about to change. A revision of the Islamic law has been proposed, and has a good possibility of being passed. Under the terms of the new law, the Koran and the Sunna will be officially translated into German, and the contents scrutinized by the state to determine whether they are in fact compatible with Austrian law.
