Final answer:
Islam was primarily spread through imperial expansion.
Step-by-step explanation:

During this period, Arab armies, motivated by religious and political goals, conquered vast territories, resulting in the establishment of Islamic rule in regions including the Middle East, North Africa, Spain, and parts of India. This expansion facilitated the dissemination of Islamic teachings and the conversion of local populations to Islam.
