What is seen in the history of Islamic nations is that most of the men of science, literature, and art were Persians, Syrians, or Egyptians who converted to Islam or maintained their ancient religions, but they flourished under the banner of Islam. This civilization is therefore an Islamic civilization. Adopting this opinion may be an injustice to the Arabs and a disdain for their heritage in some fields of civilization. The Arabs had poetry, literature, and social systems, and the Arabs were proud of the great conquests they made and the great heritage they left behind.
