When the lecture was to begin, and it was proclaimed aloud, "Hear what the heads of the schools are about to say," those present burst into tears on account of the disunion in their midst. The tears of the multitude had so mighty an effect upon Joseph ben Chiya that he arose, and publicly tendered his resignation in favor of his opponent. He received an insulting blessing as the reward of his noble resolve. "May God give you a share in the world to come," said his opponent, who now assumed his position. It was only after Abraham's death (828), that the noble Joseph was re-installed as Gaon of Pumbeditha (828-833). All disputes had ceased in the school of Sora, but they soon broke out again, and created such confusion, that Sora was without a Gaon for two years (837-839). We are in the dark as to the true reason of all this discord, but it is probable that the rise of Karaism had something to do with it. However much the Rabbanites hated the Karaite sect, and though they declared it heretical, and kept away from it, yet they adopted several of its teachings, and imitated it in others. But if Anan's sect had sown the seeds of dissension amongst the followers of the more ancient sect, it was itself not by any means free therefrom. The principal dogma of Karaism was unlimited freedom in exegesis, and the regulation of religion according to the result of honest inquiry. The result was that every Karaite constructed his Judaism according to his own interpretation of the text. Religious practice was regulated according to the clever or silly ideas of the expositor. Moreover, exegesis was yet in its infancy. The knowledge of the Hebrew language, the basis of a healthy, rational exegesis, was still scanty, and arbitrariness had every opportunity of asserting itself. Every one believed himself to be in possession of the truth, and when he did not condemn them, pitied those who did not share his views. We have a sad picture of the condition of Karaism scarcely a century after Anan's death. New sects, too, arose from it, the founders of which had strange ideas about some customs of Judaism. Musa (or Mesvi) and Ishmael, from the town of Akbara (seven miles east of Bagdad), are said to have held peculiar views about the observance of the Sabbath. What these views were we do not now know, but they approached the doctrines of the Samaritans. The two Akbarites further declared that the Pentateuchal prohibition against eating certain parts of the fat of an animal only referred to the sacrifices, and that it was permissible to use them otherwise. Musa and Ishmael found followers who lived according to their doctrines. These formed a sect within Karaism, and called themselves Akbarites.
