In the first centuries of Islam, who spread the religion?

• A. Muhammad and his followers
• B. Ali and Fatima
• C. Abu Bakr alone
• D. Umar and Uthman

Answer: (A)

The main idea here is that Islam began with Muhammad’s message and the group of people who accepted and followed him. During his life, Muhammad preached in Mecca and Medina, drawing converts and establishing a community of believers. After his death, that same group—the early followers—carried the faith outward, helping Islam spread through areas beyond Arabia, both through preaching and, later, state-led expansion under the early caliphs. So the most accurate way to describe who spread the religion in the first centuries is Muhammad and his followers, since the religion starts with his teachings and is carried forward by those who believed and acted on them.
