The symbol of the Stellar Umma Core

Old Earth monotheistic religion based on belief in one God and Muhammad, circa 1399 to 1337 BT (570 to 632 c.e.) as the last of a series of Prophets of God. It became the largest religion on Earth by the middle Information Age, and split into a number of space-based sects during the Interplanetary Period.

The post-expulsion Stella Umma was based on a combination of Orbital Islam and reformed Earth-based Islam. Many thousands of worlds are part of the Umma Core and the Umma Shell, and Umma Islamic communities can be found on millions of other worlds.
