Sefer Zivhe Tsedek, authored by Rabbi 'Abdullah Somekh, contains halakhic rulings, commentaries on Shulhan ‘arukh Yoreh De'ah, and halakhic responsa to queries from Jewish communities in Ottoman Iraq, Qajar Persia, and the Baghdadi diaspora communities in India and China. Rabbi 'Abdullah Somekh (1813-1889) was an Ottoman Baghdadi rabbi, rosh yeshiva (head of the Jewish religious academy), and halakhic scholar whose death and burial caused a municipal scandal in Baghdad. This particular edition of Sefer Zivhe Tsedek was printed posthumously in the Baghdadi printing house of Rabbi Shlomo Bekhor Hutsin in 1898 or 1899. Rabbi Hutsin (1843-1893) opened the third Hebrew language printing house in Baghdad in 1867 and printed books of Torah, science, and history in Hebrew and Judeo-Arabic in his press. His son Yehoshua continued printing books at this press, like Rabbi 'Abdullah Somekh's Zivhe Tsedek.
