The Welayat of Holy Imams has two dimensions – i.e. generation and legislation. Each one of these aspects can be examined via rational, traditional and historical approaches. The present essay studies the issue of "legislative Welayat of Imams (AS)" through a tradition-based approach in the domain of varieties of legislative Welayat. This article is concentrated on the following categories: Welayat to legislation or conferment of legislation to Imams, exegetical Welayat or scientific and religious authority, social Welayat or leadership of society. Traditional texts have proven the legislative Welayat of Prophet's Household in all these cases and eventually they demonstrate that Imams have the same status as that of Prophet Mohammad (SAW) in all affairs of Welayat but prophecy.
