I have muscadines on my property. They're really easy to grow for me here, I am in zone 8b, which means that we rarely freeze and temperatures are often in the 90s Fahrenheit in the summer. Whats different here than in the UAE is that we're likely to have it a lot more humid.
But, I live on the coast, so I have very sandy soil, so that seems similar. The only difference is that you're possibly hotter and less humid. The heat is something that the muscadines like, but the lack of humidity may be the only source of problems for you.
I think that if you can grow figs, you can grow muscadines. I don't know how it works, but if customs would allow it, I am about to go and prune mine. I have several varieties and one of them is hybridized with a bunch grape.
