Final answer:
Islam has diffused beyond its places of origin through means such as conquest, trade, and migration. This diffusion has resulted in a diverse geographic and ethnic spread of the faith.
Step-by-step explanation:
Islam has diffused beyond its places of origin through various means such as imperial conquest, trade, Sufi missionary work, migration, and intermarriage with local populations.
Muslims migrating to new lands usually established Islamic religious institutions, providing consistency for local people as well as travelers. This facilitated movement and exchange within the Islamic world.
The spread of Islam through trade routes like the Silk Roads and along sea routes, as well as its adaptation to local cultures, resulted in a great geographic and ethnic diversity of the faith.
