《金史·列传·卷二十五》
纥石烈志宁率领一万精兵，从睢阳出发，奔向宿州，中使前来督军，纥石烈志宁让他附带上奏说： 这次战役不用劳烦皇帝考虑，我只是担心李世辅逃跑。 
志宁以精兵万人，发自睢阳，趋宿州。中使来督军，志宁附奏曰： 此役不烦圣虑，臣但恐世辅遁去耳。 
Heshiliefu Zhinin led ten thousand elite soldiers from Suiyang to Shuzhou. When the royal messengers came to supervise the army, Heshiliefu Zhinin asked them to report along with him: "Don't trouble the emperor with this battle because I'm only worried that Li Shifu will run away."
