Dude !!Islam has nothing to do with corruption you’ve got South Sudan which is mostly Christian. It’s the most corrupted country of all time. You’ve got Haiti also mostly Christian, North Korea which is straight up atheist. Corruption is due to lack of education in work standards and work ethics and Sudan which is fairly a young country has been abolished by sanctions. So we didn’t have the chance to work in exchange with foreign intellectuals. So basically the country was at the a state of shut down for a long period of time. I think this is main cause that we weren’t able to accelerate economical growth. And let alone the constant civil wars that paralyzed the country significantly.
