当哈瓦津部落得知穆斯林已经攻克麦加时，他们担心自己会遭到穆斯林的袭击，营地也会被穆斯林攻入，于是着手备战，以应对穆斯林的威胁。马立克·本·奥夫·纳德里将哈瓦津和塞给夫两部落聚集起来，率领他们一路行进，直到抵达奥塔斯山谷。

When the tribe of Hawazin heard how the Muslims had liberated Makkah, they feared that they might be raided and their quarters stormed by the Muslims. Therefore, they set about countering the Muslim threat by preparing themselves for battle. Malik ibn ‘Auf al-Nadri assembled Hawazin and Thaqif together and marched with them until they reached the valley of Autas.

当哈瓦زن和ثقيف两部的大军即将来袭的消息传到穆斯林那里时，距离征服麦加已过去十五天，他们便准备迎战。马立克没有在奥塔斯山谷扎营，而是把部队向上转移到欧南山的群山之中，驻扎在山谷中最难以接近的地段，并在战略要地周密地部署兵力。他命令手下，待穆斯林进入山谷后便发起攻击，以使他们陷入混乱，从而导致队伍溃散。这一计划被精心筹划，他便在那里等待穆斯林的到来。

The news of the impending armies of Hawazin and Thaqif reached the Muslims fifteen days after the conquest of Makkah and they prepared themselves to meet them. Malik did not encamp in the valley of Autas. Instead, he moved his troops up into the hills of Hunayn in the most inaccessible part of the valley, where he organized them carefully in strategic positions. He instructed his men to attack the Muslims, once they had entered the valley so as to cause confusion among them which would lead to them breaking ranks. The plan was carefully worked out, while he waited there for the arrival of the Muslims.
