It is important for a Muslim, particularly a Twelve Imam Shiite, to know whether it is compulsory for him or not to recite a whole chapter of the Qura'n after Fateheh (the opening chapter of the Qura'n) when he performs his prayers. It is important because sometimes the prayer is performed only with the Opening Chapter. So a Muslim should know if this procedure is valid or not. Having mentioned the viewpoints of Jurists of different Islamic sects, and having evaluated their reasons, the author of this article professes his own view and proves that in accordance with the traditions quoted from the Holy prophet and his Household, it is not obligatory to recite a whole chapter.
