the methods of ahl al-bayt imams in teaching of qur'an exegesis

after the prophet death (pbuh), imam ali and other innocent             imams took efforts on protection, revival and teaching           prophetic tradition which was the interpretation of the holy   quran. they did necessary actions in this case such as:    invitation of imam ali from public to question about qur'anic exegesis, holding special sessions to teach quran     and its interpretation. on the other side, people gathered         around imam ali and he taught them jurisprudence and        qur'an.             this method of education was followed and continued by      other innocent imams, specially imam baqir and imam   sadiq in the way that they held many general and special       meeting for teaching people qur'anic instructions. many of           narratives of imams are people's questions about qur'an and hadith. people and especially many top student and pupils        attempted to learn more and more. so, as a result of this         situation a lot of students have educated.             plenty of educated excellent students had recognized as an    exegete and some of them narrated too many interpretative    traditions. clarifying and statement of the principles of the     right interpretation of prophet is one of the other important            goals of imams.             therefore, they found a comprehensive and effective system            of education which guarantee islamic society from all social,             political and cultural crisis through the time.
