Actually I want to add something on islam in Slovenia. I am writing my reply here because ‘islam in Slovenia’ is closed for any further comments.
I am a Slovene muslim myself and I have always lived in Slovenia. Bosniacs make up about 80% of Slovenian muslim population and Albanians another 10%. But majority of these people are no good muslims. Mostly, they are non educated fasiqeen and most of them have done acts which lead out of islam. I estimate that about 1% out of 50,000 people are praying regularly.
The situation is disastrous. We are waiting for muslim immigrants to come and aid us. The problem is that those practising the deen and willing to work for islam are young people (students) with insufficient financial fonds. And besides, there are too few of us.

Anyhow, Slovenes have met islam for first time when the Osmanic army came to liberate this region from Austrian rule in 10th century Hijri. In that time Slovenes were too blind to recognise the right religion. They couldn’t understand Turkish and the priests were telling them lies on these ‘barbarians’. Other major factor of kufr were Croatian (catholic) and Serbian (orthodox christian) mercenairies in sultan’s army. They were killing innocent people and robbing villages. There is no recording that these Turkish would build any mosque.
Probably some Slovene merchants embraced islam in Greece and set off for Andalus later but there are no historical sources to confirm that.

Their next meeting with islam was in 1915 AD when Bosnian soldiers came to fight against Italy (Slovenia and Bosnia were part of Austro-Hungarian Empire at that time). Bosniacs had built 2 mosques in west of country, but they were both destroyed by Italians after WWI when western Slovenia became part of Italy.

There was also 1 poet and priest in 19th century AD (Anton A?kerc) who was so inspired by islam that he risked his head and quit being a priest and a member of Catholic church. He travelled to Middle East and his last poems were at least strongly influensed by islam. If he converted to islam he was the only muslim in Slovenia. But since Slovene history is written by kufaar we cannot know for sure. They say he became an atheist.

Later, islam returned with immigrants from Bosnia (Bosnia) and later Macedonia (Torbesh, Albanian and some Turkish). Nowadays, there are about 10 converts and I am the only one from national capitol (entire population cca. 280,000; 8% muslim). People here in general dislike islam and are very racistic. As a renegade from kufr and shaytanic tradition I face many troubles in my community. But my nationality could also be my advantage sometimes.

For sure, Slovenia is an interesting country for da’wa but unfortunately quite unknown. We must hurry before devious groups like ismailis and qadiyanis start their activities here.
