摘要：Although Shiites were in bottleneck since the time of Umayyad and had permission to perform no cultural, political and scientific activity, some dynasties were emerged in early 2nd to 6th centuries in Rey and Qom, who played key role in progress of ideas and principles of Shiite. The most famous dynasties by that age were families of Al Babuye, among which narrators and philosophers and grate scientists were emerged. Elderly people and scholars of the dynasty trained many students to play important role in stabilizing and expanding narrative and juridical heritage of Shiites in Iraq and Iran. They could also give service to representatives of Imam Zaman (peace upon him) and ask about religious issues and achieve belief on them. In addition, the scientists could attract support of governors of Al Buye in Iran and Iraq to spread juridical thoughts of Shiite and meet problems of Shiites and write some books about principles of ideas of Shiite. The books have been big source for Shiites till now. For example, one can name works including Al-Amali, Al-KHesal and so on. The books have been written for rejecting idea of Sunnis about existence of Imam Zaman and beliefs about themselves, which used to consider Sunnat.
