A new addition to Encyclopaedia Iranica

KETĀB AL-EṢLĀḤan early Ismaʿili work in Arabic, the title of which can be translated as The Book of Correction, written by Abu Ḥātem Rāzi, who was a leading dāʿi in the first half of the 4th/10th century in what is now northwestern Iran. The book was intended to refute, or to “correct” (aṣlaḥa), the Ketāb al-maḥṣul by Moḥammad Nasafi (d. 332/943).
