What was the name of the new religion that united the Arab tribes?

The religion that united the Arab tribes around itself at the beginning of the 7th century is called Islam. For the first time, the ideas of Islam were presented by Muhammad in the city of Mecca. There he found his first companions. Later, Muhammad began to be perceived by the followers of the new religion as a prophet.
For the first few years, the Islamic (or Muslim) community was small and persecuted and threatened. However, then it sharply increased in number and became a serious force throughout the Arabian Peninsula. By the end of the 1560s, all Arab tribes had converted to Islam.
