It's still the case 'till now, some Qataris can't marry from x or y family!
There are still some mentalities who thinks of 1700's minds

''Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. 'Discover''

Mark Twain
