Volume four of the Let's learn about... series deals with the subject of imamate. The book comprises ten main lessons. Some of the issues discussed are: Where did Imamology begin?, The conditions and special qualities of the imams, Who selects the imam?, the Qur'an and imamate, the twelve imams and The twelfth Imam.
The lessons are very imaginative with lots of opportunities to ask questions and think of answers.
