高僧傳 10.39

10.39

晉末朔方凶奴赫連勃勃。破擭關中，斬戮無數。時始亦遇害，而刀不能傷，勃勃嗟之，普赦沙門，悉皆不殺。

At the end of the Jin, Helian Bobo of the Xiongnu of Shuofang invaded and captured Guanzhong, slaughtering countless people. At that time, Shi was also caught in the slaughter, but blades could not wound him. Bobo marveled at him and issued a universal pardon for all śramaṇas, killing none of them.
