Imam Sadiq,(PBUH) the founder of Ja'fari School, is the main pillar of Shi'a from intellectual and ideological points of view. A large corpus of Ahlul-Bayt's traditions and instructions were disseminated by him. Imam Sadiq's (article has adopted a descriptive- analytical method and PBUH) period was a very important one since various sects emerged at that time, and Imam undertook the crucial task of preserving Shi'a by defying those deviations. Among those was the Zaidi sect which had more or less expanded in those days. Analyzing Imam's approach to that expanding sect is, therefore, of high importance.
