What was Muhammad's most important teaching when compared to the other Arab beliefs of the time

A man meditating alone in a cave near Mecca received a religious vision. This vision laid the foundations for a new religion. The year was 610 and the man's name was Muhammad.

And the belief system that arose from Muhammad's ideas became the basis of one of the world's most widely practiced religions: Islam.

Muhammad was born around 570 in the city of Mecca, located on the Arabian Peninsula. Both of his parents died before Muhammad was six and he was raised by his grandfather and uncle. His family belonged to a poor clan that was active in Mecca politics.

Following the traditions of wealthy families, he spent part of his childhood living with a Bedouin family. Bedouins led fairly isolated lives as nomadic herders in the harsh Arabian desert. Muhammad's experiences among these people most likely had a strong influence on the development of Islam.

In his twenties, Muhammad began working as a merchant and soon married his employer, a rich woman named Khadijah. Over the next 20 years, he became a wealthy and respected trader, traveling throughout the Middle East. He and his wife had six children - two boys (who did not live into adulthood) and four girls. By the time he was 40, he began having religious visions that would change his life.
