Zoroastrians in Early Islamic History - Accommodation and Memory

The second Muslim caliph, Umar ibn al-Khattab, once reportedly exclaimed, ‘I do not know how to treat Zoroastrians!’ He and other Muslims encountered Zoroastrians during the conquest of Arabia but struggled to formulate a consistent policy toward the adherents of a religion that was neither biblical nor polytheistic. Some Muslims saw Zoroastrians as pagans and sought to limit interaction with them. Others found ways to incorporate them within the empire of Islamic law. Andrew D. Magnusson describes the struggle between advocates of inclusion and exclusion, the ultimate accommodation of Zoroastrians, and the reasons that Muslim historians have subsequently buried the memory of this relationship.
