Sar Shalom ben Moses HaLevi (Hebrew: שר שלום בן משה הלוי, Arabic: يحيى أبو زكري Yaḥyā Abū Zikrī; d. 1204), also called Zutta, was the last of the Egyptian geonim.
He controversially held office in Fustat as the nagid of the Egyptian community from 1170 to 1171 and again from around 1173 to 1195, during which he was excommunicated several times by Maimonides for tax farming.
Additionally, the author describes Sar Shalom (who he calls Zuta meaning "little one") as a "despotic ignoramus" blinded by his aristocratic pedigree.
[1][2][3] Letters and documents found in the Fustat Genizah provide additional details of how Sar Shalom attempted to appoint tax-farming governors in El Mahalla, Alexandria, and Bilbeis.
Since the Nagid possessed the exclusive power of appointing judges, the ban was representative of the public rejection of Sar Shalom's authority.
