By 2005, only one purpose-built mosque existed in Norway, built by the Sufi-inspired Sunni Muslim World Islamic Mission in Oslo in 1995. Minhaj-ul-Quran International established its mosque and centre in 1987. In 2000, this was the first Norwegian mosque to start performing the adhan - the call to prayer. Initially, the mosque received permission from Gamle Oslo borough to perform the adhan once a week. This was appealed to county authorities by the Progress Party. The ruling of the "fylkesmann" (county governor) of Oslo and Akershus stated that no permission was required for performing the adhan, leaving the mosque free to perform it at their own discretion. The mosque decided to limit themselves to performing the adhan once a week.
