Final answer:
Islam played a significant role in shaping the culture, language, and traditions of different ethnic groups by blending Islamic practices with indigenous traditions and incorporating aspects of Arab and Islamic culture into daily life.
Step-by-step explanation:
Islam played a significant role in shaping the culture, language, and traditions of different ethnic groups throughout history. For example, in India and Indonesia, new converts blended Islamic practices with indigenous traditions. In the Middle East and North Africa, as the early Islamic state grew, aspects of Arab and Islamic culture were incorporated into daily life while maintaining commitment to their own religious communities. The spread of Islam also led to a great geographic and ethnic diversity of the faith, with allegiance to a shared historical tradition and set of core beliefs providing unity and coherence.
