In 1951–1952 (תשי"ב by the Jewish calendar), he published his first halakha sefer, Hazon Ovadia on the laws of Passover. The book won much praise, and received the approval of the two Chief Rabbis of Israel at the time, Ben-Zion Meir Hai Uziel and Yitzhak HaLevi Herzog. Two years later he founded 'Or HaTorah' Yeshiva for gifted Sephardic Yeshiva students. This Yeshiva (which did not remain open for long) was the first of many which he established, later with the help of his sons, in order to facilitate Torah education for Sephardic Jews, in order to provide leadership for the community in future generations. In 1953-4 (תשי"ד) and 1955-6 (תשט"ז), he published the first two volumes of his major work Yabia Omer, which also received much praise.
