The historical approach of “discourse analysis” is one of the new and efficient methods in studying Imami Hadiths. This method, which is based on the theory of “Bakhtin’s competing voices”, investigates the hidden discourse in the heart of traditions through the histology of society’s beliefs at the time of repercussion of traditions and the reading of the rival discourse. In this research, we seek to analyze the discourse of hadiths of Hassan ibn Mahboub (149-224 AH) in the field of Mahdism teaching. He was one of the companions of Imam Kazem (A.S), Imam Reza (A.S) and Imam Javad (A.S), and one of the Imamate People of Consensus at his own time. The findings of this research indicate that Ibn Mahboub has reflected his Mahdism hadiths in the face of four rival discourses that sought to promote misconceptions about the promised genealogy, the appointment of Mahdi (A.S), the absence of Support of Muhammad’s Family and the uprising of the savior in the intellectual and doctrinal context of the society of that time.
