I'd like to thank the staff member , Lady Oniya & lady Beguile's Mistress for their kind observation over the thread. And all the other threads too.
is the Ummah something you, I dunno, have at the forefront of your head? Is it a real lived thing or just a theological concept? Do you see it as applying even to Muslims from a different sect? Christianity has (had?) that viewpoint as well (things like 1 Cor 1:10 or Rom 12:5) but it was never really a lived and breathed doctrine, and I'm kinda curious as to whether it has survived in Islam. My daadi talks about it quite a lot, but she draws lines closer and tighter than I've got the impression they should (for whatever meaning that word has) be drawn.
The Ummah , or the Nation , is a concept. A term that includes all Muslims , all sects , faiths and individuals. The easiest way to put it would be ' We believe in the same religion , generally. Thus we should band together under a single flag. ' At this day and age , its just something the Imam like to say , but the average Joe does not even care about it. Mixing up with everyday's life , a man does not have the mindset to think about the rest of the world. So it became a term that is thrown around when needed for an argument's sake. In reality? Most Islamic countries are not even in good terms with each others and the examples are too many to count.
Now regarding what is between Saudi Arabia and Oman. Its part of the Cooperative Council of the Arabian gulf countries. Originally it consisted of Saudi Arabia , Kuwait , UAE , Bahrain , Qatar & Oman. Iraq joined , but was expelled after the gulf war and just recently re-accepted , and Yemen also recently joined. What differs the relationship is something political more than just an Islamic bond. So , it doesn't really relate to the ' Nation ' concept.
