That's a great book, but based on churches floors in Europe. While there might be some overlap, the tile work in the Middle East is markedly different, at least to my eyes (and seven years living there).
Here's an example:

But you can just do a search on combinations of the "country, mosque, tile work" and, guaranteed, someone has taken a picture of it and posted it somewhere.
But whatever, you do, unless it's so blandly generic, have it vetted just to make sure you don't innocently offend the recipients (or other locals).
