SHAFAQNA – Seyyed ibn Tawoos (RA) narrated: When in the presence of Imam Mahdi (AJ), the topic of discussion was about the occultation of Imam (AS), one of those present asked: What is the duty of your Shia Muslims? Imam Mahdi (AJ) replied: Pray and wait for the re-appearance [1]. If say praying in personal terms is for self-purification, certainly waiting for re-appearance refers to both in terms of self-purification (self-control) and transformation/preparation (at personal and community levels).
