Is there a Muslim country that actually follows Islam?

I’m mainly talking about the leaders right now.

The Muslim countries that I know of are so corrupt and set such a bad example it makes me so sad. When people who have never befriended a Muslim think of Muslims they probably think of countries like Saudi Arabia. I keep trying to explain to people that despite the leaders being Muslim, they don’t actually follow Islam. They’re greedy and don’t represent us.

TLDR; Is there a Muslim country that actually follows Islam because seeing a region that once ruled the world because they were so advanced and knowledgeable fall this way is so upsetting.
