The "Uyun al-akhbar" is the most complete extant text by an Ismaili author on the history of the Ismaili community from its origins up to Idris 'Imad al-Din's own time in the 15th century. The seventh volume, edited here together with a summary English translation, deals in particular with the period of the three Fatimid caliphs - al-Mustansir, al-Musta'li and al-Amir - in addition to the Tayyibi Ismaili community in Yemen.
