Research and religion go hand in hand with Arabia, and the Madrasa is proof of this. Compared to the standard University, it is available an era sooner (with the Theology civic rather than the Education technology), provides 1 extra Science, and generates Faith equal to the adjacency bonus its Campus receives. If the Arabians can place their Campuses next to Mountains or Rainforests, they'll be able to enjoy a Faith bonus from their Madrasas as they work their way up the tech tree.
A madrasa (madrasah in Arabic or medrese in Turkish) is a secular institution of education, although often with a religious component. Madrasas would specialize in medicine, law, science, philosophy, religion or the education of (horrors) women. Others also taught logic, world history, foreign languages, mathematics, art, and comparative literature. The first madrasa, the Gama'at al-Qarawiyyn, was established in 859 AD by Fatimah al-Fihri, the daughter of a wealthy merchant. During the rule of the Fatimid, Ayyubid, and Mamluk dynasties, the practice of sponsoring madrasas by the ruling, wealthy elite spread across Egypt and the Middle East. The first Ottoman madrasa was founded in 1331 in Iznik, and followed the traditions of Sunni Islam. The madrasas of the Turks and Arabs would, as Europe stumbled through the Dark Ages, keep the best of Western knowledge alive, and blend it with that of the East.
