Pauline/ Paul

Explanation:

Most scholars agree that Paul actually wrote seven of the Pauline epistles, but that four of the epistles in Paul's name are pseudepigraphic (Ephesians, First Timothy, Second Timothy, and Titus) and that two other epistles are of questionable authorship (Second Thessalonians and Colossians).

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.
