Today Muslims are more backward than the tribals in India. They are hated all over the world, and seen as degenerate and oppressive. There is nothing good that has come out of them, but from people who have sidelined their own religion. Eg. Abdul Kalam, who is well-versed in Sanskrit and the Hindu religion. Azim Premji, whom you will never think of as a Muslim, because he himself downplays it.
This speaks volumes about the reality of Islam, and the harm caused by it to any society.
When the Arabs run out of oil, they will return to their Beduin-type poverty that was common until the early 1920s in Arabia. Wait and watch.
