A ray of hope beamed in the interim in the north. At a distance of about 250 miles from Mecca was a town then known as Yathirab, and later as Medina. Its population was divided into two groups, the Jews and pagans. The pagans had two clans, Aws and Khazraj, who were generally at loggerheads with each other. Every year in the month of Rajab, the Arabs swarmed like locusts into Mecca. One day in Mecca, whilst sadly but yet hopefully working among the half-traders and half-pilgrims, Muhammad came upon a group of six men who were of Khazraj. Meeting them perchance, Muhammad led them to a declivity and recited to them the verses from Koran, enumerated the blessings of a good and pious life and beckoned them to the fold. Struck by his earnestness and the truth of his words, they embraced Islam. When they returned to their native Yathirab, they spread the news, with lightning rapidity that a Prophet had arisen among the Arabs in Mecca. The town was soon agog with stories of the new faith and its wonderful leader. So the ensuing year another twelve pilgrims came to Mecca and made their vows at the same spot which had witnessed the conversion of the former six. This is called the first pledge of Aqaba, from the name of the hill on which the conference was held. The following year, 622 A.D., the Yathirabites who had adopted the new religion repaired to Mecca. In the stillness of night, when all inimical elements appeared slumbering, these seventy-two pioneers of the new faith met under the same hill. Muhammad appeared among them, and vividly described to them the risk they incurred by adopting Islam. They replied with one voice that they adopted the religion fully conscious of the dangers that surrounding them. Thus was concluded the second pledge of Aqaba.
