An unimportant circumstance revealed the moral corruption of the Jewish Babylonian chiefs. There was a lawsuit about a large inheritance, which had not been conscientiously decided by the Exilarch David. His decision was influenced by the prospect of great gain. To make his decree legal and unimpeachable, David demanded the signatures of the two Geonim to the document prepared by him. Kohen-Zedek signed without objection; Saadiah, however, would not countenance the injustice. On being pressed by the parties, he gave the reason for his refusal. The Exilarch David, who now was doubly interested in obtaining his signature, sent his son Judah to ask him to sign the document without delay. Saadiah calmly replied that the Law forbade him to do such things, as it is said, "Ye shall not respect persons in judgment." Once more David sent his son to Saadiah to threaten him with deposition in case he still refused. Judah at first assumed a quiet demeanor, and begged Saadiah not to be the cause of quarrels in the community. When, however, he found him determined, he raised his hand against Saadiah, and vehemently demanded his signature. Saadiah's servants soon removed Judah, and locked the door of the meeting hall. David ben Zaccaï, who felt himself insulted, deprived the Gaon of his office. He excommunicated him and appointed a young man, Joseph ben Jacob ben Satia, as his successor. Saadiah, however, was not the man to be terrified by force. He, in turn, declared David to be no longer Exilarch, and named Josiah Hassan as Prince of the Captivity (930). Two factions immediately arose in Babylonia, the one for Saadiah, the other for David. On Saadiah's side were ranged the members of the academy of Sora and many respected and learned men of Bagdad, amongst whom were the sons of Netira. Opposed to him were Aaron Ibn-Sarjadu and his party, and probably also Kohen-Zedek and the members of the college of Pumbeditha. Both parties appealed to the Caliph Al-Muktadir, and bribed his favorites and courtiers to gain him over to their side. Ibn-Sarjadu spent 10,000 ducats to effect Saadiah's deposition. The Caliph wished to hear both parties, and ordered a formal trial to take place in Bagdad under the presidency of the vizir, who was assisted by many important men. The dispute was not settled. This was probably owing to the fact that the Caliph Al-Muktadir was constantly changing his vizirs during the last two years of his reign, and to the disturbed state of the capital during this time (930-932). Saadiah asserted his authority as Gaon, though there was a rival Gaon in the person of Joseph ben Satia. There were likewise rival Exilarchs, David and his brother Josiah Hassan.
