First of all, we would like to note that Islam is a great Divine blessing given to this world. It is the Path of Righteousness chosen for all people in all times. Islamic civilization is not based on the ashes of any other civilization; rather, it teaches people how to be civilized. It is this civilization that penetrate all hearts and minds. No one can claim that Islam introduces its civilization on the dead body of any other civilization or the shedding of the blood of a single person unjustly.
In Islam, no one is forced to believe in something other than his own choice. No one is obliged to choose anything against his own free will. Moreover, Islam gives a place to every individual or group to make the best use of his/their own talents and power of creativity. There is no restrictions or limitations due to race, geographical location, color, religion or whatever. Islam gives an open chance to every person serve the welfare of the whole tapestry of the society.

Elaborating more on this point, we would like to cite for you the following:

“Islam was destined to become a world religion and to create a civilization which stretched from one end of the globe to the other. Already during the early Muslim caliphates, first the Arabs, then the Persians and later the Turks set about to create classical Islamic civilization. Later, in the 13th century, both Africa and India became great centers of Islamic civilization and soon thereafter Muslim kingdoms were established in the Malay-Indonesian world while Chinese Muslims flourished throughout China.

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 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-Muslims and the People of the Book participated in the intellectual activity whose fruits were reaped by everyone. The scientific climate was great that every person worked for the benefit of this civilization that belonged to all.

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.
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 never 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.”
