I don't see this as a big problem. Especially not in the near future.
Do you have some hard numbers for the amount of Muslims (or people from Islam-dominated countries) coming to AND being allowed to stay in Europe?
I could imagine that legal immigrants from non-European countries like Russia, the Americas and other East-Asian countries outweight the amount of Muslims (refugees and non-refugees) migrating to Europe.

The fertility rate is a bit higher, true but that's going to take several centuries to make an impact.

I think this flowcharts is giving reasons to worry especially in France where 8% of the population is muslim, especially the terrorism chart worries me. http://www.economist.com/blogs/graphicdetail/2015/01/daily-chart-2,
