In what government system, power is divided between two levels: national and local

The answer is federalism, from the Latin foedus, which can be translated in English as deal or alliance. In a federal government, both the central, or federal, government and the regional, or local, governments, share the power in equal terms, and, as a result, their influence is limited.

is this from a story?

if so, can you tell which one?

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
