Islam History in Brief - Any History of Islam has to be brief it was the Religion of Nabi Adam (as)
Global Religion
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.
