Abul Ash‘ab Saadi narrates from his father that Ahnaf bin Qais fought against the people of Marw Al-Rudh, Taleqan, Faryab and Jowzjan well into the night, until Allah the Almighty inflicted the enemy with defeat.

Ahnaf bin Qais dispatched the cavalry under the command of Aqra bin Habis to Jowzjan. Aqra was sent to deal with the remaining army that Ahnaf had already defeated. Thus Aqra encountered them in a ferocious battle, in which many from the cavalry were martyred. Eventually, Allah the Almighty granted the Muslims victory.
