The Arabs who settled along the southern and western coasts of the peninsula had reached in the sixth century a considerable degree of civilization. They practiced agriculture and carried on a flourishing trade across the Red Sea and even to distant India. Between these sedentary Arabs and the Bedouins raged constant feuds, leading to much petty warfare. Nevertheless the hundreds of tribes throughout the peninsula preserved a feeling of national unity, which was greatly strengthened by Mohammed's appearance on the scene. ARABIAN HEATHENISM The city of Mecca, located about fifty miles from the Red Sea, was a commercial metropolis and the center of Arabian heathenism. Every year the Arab tribes ceased fighting for four months, and went up to Mecca to buy and sell and visit the famous sanctuary called the Kaaba. Here were three hundred and sixty idols and a small, black stone (probably a meteorite), which legend declared had been brought from heaven. The stone was originally white, but the sins of the people who touched it had blackened it. Although most of the Arabs were idolaters, yet some of them recognized the "Unknown God" of the Semites, Allah, the Creator of all things. Arabia at this time contained many Jews, Zoroastrians, and Christians, who helped to spread abroad the conception of one God and thus to prepare the way for a prophet of a new religion. 131. MOHAMMED: PROPHET AND STATESMAN, 622-632 A.D. EARLY LIFE OF MOHAMMED Mohammed, [2] born at Mecca about 570 A.D., belonged to the tribe of the Koreish, who had long been guardians of the sacred Kaaba. Left an orphan at an early age, the future prophet was obliged to earn his own living. He served first as a shepherd on the hillsides of Mecca. This occupation, though lowly, gave him the love of solitude, and helped to nourish in his soul that appreciation of nature which later found expression in so many of his utterances. While still a youth he became a camel-driver and twice crossed the deserts with caravans to Syria. Doubtless he made many acquaintances on these journeys and picked up much useful information. Mohammed, however, did not receive a regular education; it is doubtful whether he could read or write. His marriage, when about twenty-five years of age, to a rich widow, named Khadija, brought him wealth and consideration. For some time, henceforth, he led the life of a prosperous merchant of Mecca.
