How religion can be both a unifying and a dividing force?

Religion is uniting because they allow a group of people of a different race to believe in the same thing. It is probably the most divisive problem because everyone thinks that they are correct and others are incorrect; this is how Christians, Jews, and Muslims usually conflict with each other even though they are similar.

Explanation:

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.
