Do you think Muslims will dominate the world again like they used before?

Ok, I have a suggestion for OP: Turn off Faux News and Infowars and Breitbart and pay attention to reputable news sources. Something like BBC or even CNN. No, Islam isn't a legitimate threat to "dominate the world."

The last time Islam was especially influential was over a thousand years ago. Know why it was influential? Because they were less fundamentalist, more open minded and Baghdad was the center of the scientific world. I mean, hell, they even allowed freedom of religion, something that was completely foreign to the Christian parts of the world at the time. Since then, they've rejected science in favor of dogmatism and they aren't any kind of world power now.

So, if Islam ever does get powerful enough to be a major influence on western civilization, they're going to have to get a lot less dogmatic and a lot more open minded. And if they do that, I don't see their domination being especially harmful.
