How would cooperation between the hindus and muslims build a rich and powerful empire

The cooperation between the Hindus and the Muslims would help build a rich and powerful empire because, the worlds major religions are Islam and Hinduism and because of that if two combine it makes a powerful group of people and they all have different understanding and thinking. Because of the differences between the two groups, they can come up with pretty unique ideas, which can help a lot and these two groups arent heard as much as other groups. Believe me, many of these people have unique ideas and arent heard or they just keep it to themselves. In conclusion they can build a rich and powerful empire because if their differences, beliefs, and morals they've been taught.
