Sayf said: He then distributed the proceeds of the two caskets among the combatants, so that each cavalryman received 4,000 dirhams from their sale price.
Al-Shaʿbi said: From the original booty the horseman’s share amounted to 6,000, while the foot-soldier took 2,000, and the Muslims on that day numbered 30,000.
He added: Nihavand was conquered at the beginning of the year 19 AH, seven years after ʿUmar had assumed the caliphate. Sayf transmitted the same report from ʿAmr ibn Muḥammad on Al-Shaʿbi’s authority.
And through this same chain Al-Shaʿbi said: When the captives of Nihavand (1) were brought to Madinah, Abu Luʾluʾah—Fayruz, the servant of al-Mughīrah ibn Shuʿbah—would never meet one of their children without rubbing the child’s head, weeping, and saying, “ʿUmar has eaten my liver!”
Abu Luʾluʾah himself was originally from Nihavand; the Byzantines had taken him prisoner in the days of the Persians, and later the Muslims captured him, so he was ascribed to the place where he had been enslaved. (2)
They added: After that battle the Persians never again recovered, and ʿUmar granted those who had distinguished themselves an extra 2,000 (3) as a mark of honor and in recognition of their valor.
[The Conquest of Isfahan (4)]
In the same year, after Nihavand, the Muslims also took the city of Jay—namely Isfahan—following heavy fighting and many events. Its people concluded a treaty with the Muslims, and ʿAbd Allah ibn ʿAbd Allah wrote them a deed of safety and peace, while thirty men fled to Kirman, refusing to make peace with the Muslims.
Some said that the conqueror of Isfahan (5) was al-Nuʿmān ibn Muqarrin and that he was killed there; that the leader of the Magians, Dhu al-Ḥājibayn, fell from his horse, his belly split open, and he died, whereupon his troops scattered. The sounder view, however, is that Isfahan was taken by ʿAbd Allah ibn ʿAbd Allah ibn ʿItbān, who had been the governor of Kufah.
During that same year Abu Musa captured Qumm and Qashan (6), and Suhayl ibn ʿAdi seized the city of Kirman (7).
Ibn Jarir (8), citing al-Waqidi, records that ʿAmr ibn al-ʿAs marched with an army to Tripoli, and that in Barqah he secured the city by treaty on the basis of an annual payment of 13,000 dinars.
