This book is about the beliefs of Ismailis. Two major sects within the Ismailis are the Agha Khanis who believe in 49 Imams and the Bohras who believe in 21 Imams. However both the Agha Khanis and the Bohras believe Ismail as an Imam, who was the son of Imam al-Sadiq (as) and they reject Musa al-Kadhim s/o Imam al-Sadiq (as). This book investigates the authenticity of the Ismaili/Fatimid Imams whether they were really divine.
