Plant matter such as hawthorne and oak have been used for such purposes. And garlic of course.

Then there is the restriction preventing vampires from entering sacred ground. I'm sure this would include mosques as well as churches.

It all comes down to the "power" that does the repelling. If you consider Islam, it is a religion that taps into the same deity. If you look at the things that repel vampires, they are tools from "God's universe" used to repel or otherwise fight evil.
