Khuzestan Central Persia Caucasus Pars Khorasan Other geographies The Battle of Ray was fought between the Sasanians and the Rashidun Caliphate in 651.

In 651, Farrukhzad, the spahbed of Khorasan, and minister of Yazdegerd III, mutinied and left for Tabaristan.

On his way to Tabaristan, he met the Arab general Nu'aym near Qazvin, and made peace with him.

Farrukhzad led some of Nu'aim's cavalry by a little-known route into the city, from whence they emerged to attack the defenders' rear, causing great slaughter.

To set an example, Nu'aym ordered the destruction of the Old Town, which called "al-Atiqah" by the Arabs, (perhaps the aristocratic quarter of Ray).
