Despite the long absence of the Imām of the Age (aj) and the events and hardships that have struck the umma, God (swt) has granted this umma men who will preserve it from being lost, strengthen it and lead it to goodness and righteousness. In this book, Āyatullāh Sayyid Munīr al-Khabbāz gives an extended overview into the concept of the Marjʿiyyah, and discusses the character and qualifications of Grand Āyatullāh Sayyid ʿAlī al-Sistānī.
