My choice of Muhammad (PBUH) to lead the list of the world’s most influential persons may surprise some readers and may be questioned by others, but he was the only man in history who was supremely successful on both the religious and secular levels. Of humble origins, the Holy Prophet (PBUH) founded and promulgated one of the world’s great religions, and became an immensely effective political leader.
Today, thirteen centuries after his death, his influence is still powerful and pervasive. Muhammad (PBUH) was born in the year 570, in the city of Mecca, in southern Arabia, at that time a backward area of the world, far from the centers of trade, art, and learning. Orphaned at age six, he was reared in modest surroundings. Islamic tradition tells us that he was illiterate. His economic position improved when, at age twenty-five, he married a wealthy widow.
Nevertheless, as he approached forty, there was little outward indication that he was a remarkable person. Most Arabs at that time were pagans, who believed in many gods. There were, however, in Mecca, a small number of Jews and Christians; it was from them no doubt that Prophet Muhammad (PBUH) first learned of a single, omnipotent God who ruled the entire universe.
When he was forty years old, Muhammad (PBUH) became convinced that this one true God (Allah) was speaking to him, and had chosen him to spread the true faith. For three years, Muhammad (PBUH) preached only to close friends and associates. Then, about 613, he began preaching in public. As he slowly gained converts, the Meccan authorities came to consider him a dangerous nuisance. In 622, fearing for his safety, the Prophet (PBUH) fled to Medina (a city some 200 miles north of Mecca), where he had been offered a position of considerable political power.
This flight, called the Hegira, was the turning point of the Prophet’s (PBUH) life. In Mecca, he had had few followers. In Medina, he had many more, and he soon acquired an influence that made him a virtual dictator. During the next few years, while the Prophet’s (PBUH) following grew rapidly, a series of battles were fought between Medina and Mecca. This was ended in 630 with the Holy Prophet’s (PBUH) triumphant return to Mecca as conqueror. The remaining two and one-half years of his life witnessed the rapid conversion of the Arab tribes to the new religion.
When the Prophet (PBUH) died, in 632, he was the effective ruler of all of southern Arabia. The Bedouin tribesmen of Arabia had a reputation as fierce warriors. But their number was small; and plagued by disunity and internecine warfare, they had been no match for the larger armies of the kingdoms in the settled agricultural areas to the north. However, unified by Prophet Muhammad (PBUH) for the first time in history, and inspired by their fervent belief in the one true God, these small Arab armies now embarked upon one of the most astonishing series of conquests in human history.
Numerically, the Arabs were no match for their opponents. On the field of battle, though, the inspired Arabs rapidly conquered all of Mesopotamia, Syria, and Palestine. By 642, Egypt had been wrested from the Byzantine Empire, while the Persian armies had been crushed at the key battles of Qadisiya in 637, and Nehavend in 642.
But even these enormous conquests, which were made under the leadership of the Prophet’s close friends and immediate successors, did not mark the end of the Arab advance. By 711, the Arab armies had swept completely across North Africa to the Atlantic Ocean There they turned north and, crossing the Strait of Gibraltar, overwhelmed the Visigothic kingdom in Spain.
