From a speech delivered in Zurich during his recent trip to Davos:
"I again call this out from Zurich: Islam is Europe's indigenous religion, and it will continue to be its indigenous religion. From Andalusia to the Ottomans, and, half a century ago with the holy march of our people who came here from every corner of Anatolia. The sound of the azan [Islamic call to prayer], brought by these heroes to Europe, the domes of the mosques with which they dotted this continent, will all be protected. We will continue to fight against all the hands that reach out to harm them [the mosques]. I kiss the foreheads of my brothers who carried the tekbir [i.e. the call "Allahu Akbar"] to Zurich. May Allah bless those who raised you. Blessed be those who came here with just a suitcase, in poverty, but with rich hearts filled with their faith [Islam]. How holy those people were, who came and sowed the seeds here, which will, with Allah's help, continue to grow into a huge tree of justice in the center of Europe. No one will be able to stop this."
