Islam is a religion for all people from whatever race or background they might be. That is why Islamic civilization is based on a unity which stands completely against any racial or ethnic discrimination. Such major racial and ethnic groups as the Arabs, Persians, Turks, Africans, Indians, Chinese and Malays in addition to numerous smaller units embraced Islam and contributed to the building of Islamic civilization. Moreover, Islam was not opposed to learning from the earlier civilizations and incorporating their science, learning, and culture into its own world view, as long as they did not oppose the principles of Islam. Each ethnic and racial group which embraced Islam made its contribution to the one Islamic civilization to which everyone belonged. The sense of brotherhood and sisterhood was so much emphasized that it overcame all local attachments to a particular tribe, race, or language--all of which became subservient to the universal brotherhood and sisterhood of Islam.
The global civilization thus created by Islam permitted people of diverse ethnic backgrounds to work together in cultivating various arts and sciences. Although the civilization was profoundly Islamic, even non-Muslim "people of the book" participated in the intellectual activity whose fruits belonged to everyone. The scientific climate was reminiscent of the present situation in America where scientists and men and women of learning from all over the world are active in the advancement of knowledge which belongs to everyone.
The global civilization created by Islam also succeeded in activating the mind and thought of the people who entered its fold. As a result of Islam, the nomadic Arabs became torch-bearers of science and learning. The Persians who had created a great civilization before the rise of Islam nevertheless produced much more science and learning in the Islamic period than before. The same can be said of the Turks and other peoples who embraced Islam. The religion of Islam was itself responsible not only for the creation of a world civilization in which people of many different ethnic backgrounds participated, but it played a central role in developing intellectual and cultural life on a scale not seen before. For some eight hundred years Arabic remained the major intellectual and scientific language of the world. During the centuries following the rise of Islam, Muslim dynasties ruling in various parts of the Islamic world bore witness to the flowering of Islamic culture and thought. In fact this tradition of intellectual activity was eclipsed only at the beginning of modern times as a result of the weakening of faith among Muslims combined with external domination. And today this activity has begun anew in many parts of the Islamic world now that the Muslims have regained their political independence.
