There are three main ways for Arabs to educate: first, ordinary people usually send their children to mosques for education; Second, the children of caliphs or nobles can ask tutors to educate them; Third, learn from Bedouins. The caliph of the former Umayyad dynasty often sent his sons to desert areas to learn pure Arabic and riding and shooting skills from Bedouins. Among them, mosque education is the most important, because mosque education is free and can be enjoyed by poor children.
