Blackstone is a meteorite. Before the fourth century, Islam did not appear. At that time, the Arabian Peninsula generally believed in this kind of stone and regarded it as the messenger and hand of God, so there was also a tradition of regular worship. The patron saint stone is a great right.
After the 5th century AD, Muhammad founded Islam, which was not recognized by the Holy Stone at first, so his parishioners began a long-term struggle, and then attacked Mecca, and the two sides were evenly matched. Later, after consultation, "Blackstone" became a sacred object of Islam, and Mecca accepted Muhammad and his religion.
