It has been narrated series of memoirs by Imam’s pupils and associates that Imam had well command over various discipline of theology such as jurisprudence, mysticism, Islamic philosophy and morality.
But he never mixed up the issues and also wanted other scholars to have specialization and well command over the matters without mixing the matters.
Imam also wanted seminary students to have good knowledge of matters before rendering their views about certain topics.
In addition to have command on various religious and Islamic branches of knowledge, Imam wanted clergymen to be knowledgeable about the today’s world affairs as well.
