The prophet Muhammad was always teaching the Muslims that all the people are equal in humanity & that they are all the sons of Adam who was created from dust & that all kinds of oppression are strictly forbidden.against any human. He assured these golden rules & others in His last address to Muslims in the valediction pilgrimage, this is regarding to all people regardless of their religions, races, colors...etc.
I am a Muslim, more than happy to help you! :) And you are welcome:)
Mohammad's teachings originally were not adopted by all Arab people. For these teaching to become widespread, many factors were needed. One of the reasons why the teachings spread was because of conquests. In general, the conquest and invasions were not motivated by religion as much as by economic concerns. However, with the arrival of new people, new ideas spread as well.
These ideas were also spread due to trade and commerce. Arab people had long been engaged in commerce among themselves, which led to Islam spreading faster than it would have in a different region. Finally, as Muslim people began to enjoy a higher level of cultural development, many people went to study at their schools, further spreading its culture, including Islam. All of these reasons led to a unification of the Arab people under Islam.
