Mohammed went home. He was greatly distressed. Yet his fortunes were not ruined. His sanctity was still a valuable and, unless he chose otherwise, an inalienable asset. The renowned Sheikh had a rival--nearly as holy and more enterprising than himself. From him the young priest might expect a warm welcome. Nevertheless he did not yet abandon his former superior. Placing a heavy wooden collar on his neck, clad in sackcloth and sprinkled with ashes, he again returned to his spiritual leader, and in this penitential guise implored pardon. He was ignominiously ejected. Nor did he venture to revisit the unforgiving Sheikh. But it happened that in a few weeks Sherif had occasion to journey to the island of Abba. His former disciple appeared suddenly before him, still clad in sackcloth and defiled by ashes. Careless of his plain misery, and unmoved by his loyalty, which was the more remarkable since it was disinterested, the implacable Sheikh poured forth a stream of invective. Among many insults, one went home: 'Be off, you wretched Dongolawi.' Although the natives of the Dongola province were despised and disliked in the Southern Soudan, it is not at first apparent why Mohammed should have resented so bitterly the allusion to his birthplace. But abuse by class is a dangerous though effective practice. A man will perhaps tolerate an offensive word applied to himself, but will be infuriated if his nation, his rank, or his profession is insulted. Mohammed Ahmed rose. All that man could do to make amends he had done. Now he had been publicly called 'a wretched Dongolawi.' Henceforth he would afflict Sherif with his repentance no longer. Reaching his house, he informed his disciples--for they had not abandoned him in all his trouble--that the Sheikh had finally cast him off, and that he would now take his discarded allegiance elsewhere. The rival, the Sheikh el Koreishi, lived near Mesalamia. He was jealous of Sherif and envied him his sanctimonious disciples. He was therefore delighted to receive a letter from Mohammed Ahmed announcing his breach with his former superior and offering his most devoted services. He returned a cordial invitation, and the priest of Abba island made all preparation for the journey. This new development seems to have startled the unforgiving Sherif. It was no part of his policy to alienate his followers, still less to add to those of his rival. After all, the quality of mercy was high and noble. He would at last graciously forgive the impulsive but repentant disciple. He wrote him a letter to this effect. But it was now too late. Mohammed replied with grave dignity that he had committed no crime, that he sought no forgiveness, and that 'a wretched Dongolawi' would not offend by his presence the renowned Sheikh el Sherif. After this indulgence he departed to Mesalamia.
