[Abu 'Eisa said:] This Hadith is Hasan Gharib. We do not know of it except as a narration of Yazid bin Abi Ziyad. And the meaning of his saying: "The people turned to escape" is that they fled from the fighting. As for the meaning of his saying: "Rather you are Al-'Akkarun," the 'Akkar is the one who flees to his Imam in order that he may help him, it does not mean fleeing from the advancing army.
