After a time the number of his followers began to increase. People came from distant parts of Arabia and from neighboring countries to hear him. One day six of the chief men of Medina (Me-di'-na), one of the largest cities of Arabia, listened earnestly to his preaching and were converted. When they returned home they talked of the new religion to their fellow-citizens, and a great many of them became believers.

But the people of Mecca, Mohammed's own home, were nearly all opposed to him. They would not believe what he preached, and they called him an impostor. The people of the tribe to which he himself belonged were the most bitter against him. They even threatened to put him to death as an enemy of the gods.

About this time Mohammed's uncle and wife died, and he had then hardly any friends in Mecca. He therefore resolved to leave that city and go to Medina. Numbers of the people there believed his doctrines and wished him to come and live among them. So he secretly left his native town and fled from his enemies. With a few faithful companions he made his escape to Medina.

It was in the year of our Lord 622 that Mohammed fled from Mecca. This event is very important in Mohammedan history. It is called "the flight of the prophet," or "the Hejira (Hej'-i-ra)," a word which means FLIGHT. The Hejira is the beginning of the Mohammedan era; and so in all countries where the rulers and people are Mohammedans, the years are counted from the Hejira instead of from the birth of Christ.

On his arrival in Medina the people received Mohammed with great rejoicing. He lived there the remainder of his life. A splendid church was built for him in Medina. It was called a mosque, and all Mohammedan churches, or places of worship, are called by this name. It means a place for prostration or prayer.

Mohammed thought that it was right to spread his religion by force, and to make war on "unbelievers", as he called all people who did not accept his teaching. He therefore got together an army and fought battles and unbelievers. He gained many victories. He marched against Mecca with an army of ten thousand men, and the city surrendered with little resistance. The people then joined his religion and destroyed their idols. Before very long all the inhabitants of Arabia and many of the people of the neighboring countries became Mohammedans.

Mohammed died in Medina in the year of our Lord 632, or year 11 of the Hejira. He was buried in the mosque in which he had held religious services for so many years; and Medina has ever since been honored, because it contains the tomb of the Prophet. It is believed by his followers that the body still lies in the coffin in the same state as when it was first buried. There is also a story that the coffin of Mohammed rests somewhere between heaven and earth, suspended in the air. But this fable was invented by enemies to bring ridicule on the prophet and his religion.

The tomb of Mohammed is visited every year by people from all Mohammedan countries. Mecca, the birthplace of the prophet, is also visited by vast numbers of pilgrims. Every Mussulman is bound by his religion to make a visit or pilgrimage to Mecca at least once in his life. Whenever a Mussulman prays, no matter in what part of the world he may be, he turns his face towards Mecca, as if he were always thinking of going there.

Good Mohammedans pray five times every day, and there is a church officer called a muezzin (mu-ez'-zin), who gives them notice of the hour for prayer. This he does by going on the platform, or balcony, of the minaret, or tower, of the mosque and chanting in a loud voice such words as these:

"Come to prayer, come to prayer. There is no god but God. He giveth life, and he dieth not. I praise his perfection. God is great."

In Mecca there is a mosque called the Great Mosque. It is a large enclosure in the form of a quadrangle, or square, which can hold 35,000 persons. It is enclosed by arcades with pillars of marble and granite, and has nineteen gates, each with a minaret or pointed tower above it.

Within this enclosure is a famous building called the "Kaaba (Ka'-a-ba)," or cube. It is nearly a cube in shape. It its wall, at one corner, is the celebrated "Black Stone." Moslems regard this stone with the greatest reverence. They say that it came down from heaven. It is said to have been once white, but has become dark from being wept upon and touched by so many millions of pilgrims. It really is reddish-brown in color.

Before the time of Mohammed the Kaaba was a pagan temple; but when he took possession of Mecca he made the old temple the centre of worship for his own religion.

After Mohammed died a person was appointed to be his successor as head of the Moslem church. He was called the caliph, a word which means SUCCESSOR; and this title has been borne ever since by the religious chief of the Mohammedans. In modern times the sultans or rulers of Turkey have been commonly regarded as the caliphs. Arab scholars, however, say that really the sherif (she-rif'), i.e., the governor of Mecca, is entitled by the Koran to hold this position.
