What is the result of 'undressing' a belief to words only?

The "Universal Declaration of Human Rights" are only valid for the humans that

live in the countries that signed that declaration.

Some Muslim countries have an alternative "Universal Declaration of Human Rights" where the Sharia can override human rights in that declaration. ( Cairo Declaration of Human Rights in Islam ).

When it comes to stoning people to death in western eyes this is barbaric and not in line with the "Universal Declaration of Human Rights".

But in a country like Iran it is inline ( under some strict conditions ) with the "Universal Declaration of Human Rights".

So it does not make sense to refer to the "Universal Declaration of Human Rights" when protesting against stoning people to death.

Do we live in 2 different worlds ?

Can a belief be undressed until they are empty words only, liberated from any human interpretation ?

your thoughts please.
