The people of Medina received Mohammed with joyous enthusiasm; his entrance into the town resembled that of a triumphant prince rather than a poor fugitive. Soon the rest of his friends and followers gathered round him, amongst them Ali whom the Koreish had allowed to go unharmed, Omar, with his beautiful daughter Hafsa, whom some time afterward the prophet included in the number of his wives, and Othman with his wife Rokayyah. When the last-named died in the following year, Mohammed gave his second daughter Um Kolthum in marriage to his faithful comrade. The case containing the inspired sayings of the _Koran_ was entrusted to the care of Hafsa. [Sidenote: [622-624 A.D.]] The prophet’s presence had the most beneficial results for Medina. The two tribes of the Khazraj and the Aus, who in former years had often engaged in bloody conflicts, were united in the new faith as the faithful “helpers” of God’s messenger, and in conjunction with the emigrants from Mecca (Mohajira) formed the kernel of the Moslems. At first Mohammed attempted to win over the numerous Jews of Medina to his cause, and for this reason paid attention in many respects to the Mosaic law; he continued the observance of the Sabbath, and made Jerusalem the Kibla, _i.e._, the holy place, towards which the faithful had to turn their faces when they prayed. But when the Jews refused to recognise him as the expected Messiah as they had formerly refused to recognise Jesus, but rather made the new prophet an object of their scorn, he once more turned to the old Arab faith. He removed the Kibla to Mecca, appointed Friday as the day of devotion and religious observance, and eventually wielded the scourge of religious persecution over Jews and heathens without distinction. Many of the emigrant Meccans were overtaken by illness and homesickness in this foreign land, and in order to make up to them for the loss of their relatives and belongings, Mohammed founded a system of brotherhood among fifty-four believers from Mecca and a like number from Medina, so that two men united in this “brotherhood of faith” should stand closer to each other, even in the matter of inheritance, than blood relations,--an institution which lasted, however, only until the foreigners had settled into the new life.
