Abstract: Hadīth al-Thaqalayn is one of the traditions that the Prophet Mohammad (P.B.U.H.), repeatedly, has insisted on. In this tradition, he invites Muslems to follow the holy Qur’ān and Ahl al-Bayt in order to rescue them from misleading. After mentioning different accounts of this tradition, their correctness is examined in this paper. Then, the claim of contradiction between Hadīth al-Thaqalayn and tradition of following Scripture and exemplary practice of the Prophet is rejected. Finally, it is proved that Hadīth al-Thaqalayn implies the Imamate and immediate caliphate of the Commander of the Faithful, Ali and the Ahl al-Bayt(A.S.).
