Battle of Sillabra and the death of Nafi' ibn al-Azraq

Al-Dinawari reports that al-Muhallab made it a condition for fighting the Azariqa that he choose his men and keep whatever land he won; he raised twenty thousand men, eight thousand of them of the Azd, with his son al-Mughira leading the vanguard of three thousand. ¹ He stayed at the river for forty days, then met Nafi' at a place the editor reads as Sillabra; al-Muhallab was struck in the face and fainted, and the Azariqa's leader Nafi' ibn al-Azraq was killed. ² Ibn al-Zubayr then dismissed al-Harith from Basra and gave Mus'ab both Iraqs. ³
