No. Couldn't you say God might have wanted people to spread that culture so that everyone would be raised in it?
Arab culture matters for shit, what the book professes does.
Arabs are just a very (even if significant) minor minority of the muslim population around the world (all with quite different cultures, even if religion effect culture quite a bit, all who converted at some point, where they werent "part of the culture"). Anyone reading it, and finding solace in it and converting, doesnt have to understand a culture, but what it preaches. Its for EVERYONE.
Thats the whole problem about religion, and Islam in particular, for centuries, even millenia, the culture being misintepreted as the religion, or excusing cultural practices and ways to of the religion, even when its vastly contradictory to it. The list is long.
