There follows a tradition which has become obscured with the passing of time, and whose import we can only dimly investigate.  Abu Sofian was returning somewhat uneasily to Mecca when he encountered the chief of the Khozaa, the outraged tribe.  An interview of some length is reported, and it is supposed that the chief represented to the Meccan citizen the hopelessness of his resistance and the advantages in belonging to the party that was rapidly bringing all Arabia under its sway.  Abu Sofian listened, and it may be that the chief’s words induced him to consider seriously the possibility of ranging himself beneath the banner of the Prophet.

Meanwhile Mahomet had summoned all the matchless energy of which he was capable, and set on foot preparations for the overwhelming of Mecca.  Every Believer was called to arms; equipment, horses, camels, stores were gathered in vast concourse upon the outskirts of Medina, awaiting only the command of the Prophet to go up against the scornful city whose humiliation was at hand.  The order to march was given on January 1, 630, and soon the whole army was bearing down upon Mecca with that rapidity which continually characterised the Prophet’s actions, and which was more than ever necessary now in face of the difficult task to be performed.  In a week the Prophet, with Zeinab and Dram Salma as his companions, at the head of 10,000 men, the largest army ever seen in Medina, arrived within a stage of his goal.  He encamped at Mar Azzahran and there rested his army from the long desert march, the toilsome and difficult route connecting the two long-sundered cities that had given feature to the origin and growth of Islam.  While he was there he received what was perhaps the most important asset since the conversion of Khalid.  Abbas, his uncle, still timorous and vacillating, but now impelled into a firmer courage by the powerful agency of Mahomet’s recent triumphs, quitted Mecca with his following and joined his nephew, professing the creed of Islam, and enjoining it also upon those who accompanied him.

The conversion did not come as a surprise to Mahomet.  He had been watching carefully by means of his spies the trend of events in Mecca, and he knew that the allegiance of Abbas was his whenever he should collect sufficient force to demonstrate his superiority.  Abbas loved the winning cause.  When Mahomet was obscure and persecuted he had befriended him as far as personal protection, but his was not the nature to venture upon a hazardous enterprise such as the Prophet’s attempt to found a new religious community in another city.  Now, however, that the undertaking had proved so completely victorious that it threatened to make of Mecca the weaker side, Abbas, with the solemnity which falls upon such people when self-interest points the same way as previous inclination, threw in his lot with Islam.

The Muslim rested that night at Mar Azzahran, kindling their camp-fires upon the crest of a hill whose summit could be seen from the holy city.  The glare flamed red against the purple night sky, and by its ominous glow Abu Sofian ventured beyond the city’s boundaries to reconnoitre.  Before he could penetrate as far as the Muslim encampment he was met by Abbas, who took him straightway to Mahomet.  When the morning came the Prophet sent for his rival and greeted him with contempt:
