Since 970 CE., students of philosophy, Islamic law, history, and Arabic have gathered at Al Azhar, the beautiful and distinguished university in Cairo’s old city. For many years, it was also the largest college in the world. Candidates for admission have traditionally faced a very challenging qualifying exam; entering students are required to recite the entire Koran. Even besides the length, Arabic is not the first language for many of the best Muslim students. And the Arabic used in the Koran is completely different from normal, spoken Arabic. Put that together, and this is truly a difficult test.
