《元史·列传·卷十一》
受命后出朝，在回府途中，遇回回六人，因犯诬告罪将受到惩处。速哥忙令暂缓其刑，上朝奏请太宗宽免其罪，并说： 此六人皆西域名流，若因小罪而诛杀，有失朝廷怀柔远人之意。 
受命方出，有回回六人讼事不实，将抵罪，遇诸途，急止监者曰： 姑缓其刑，当入奏。 复见帝曰： 此六人者，名著西域，徒以小罪尽诛之，恐非所以怀远人也。
After receiving the order, he left the court and met six Huihui people on his way back to the government office. They were to be punished for making false accusations. Su Ge hurriedly ordered the sentence to be suspended for the time being and went to the court to ask Taizong to pardon them, saying: "These six people are all celebrities in the Western Regions. If they are executed for minor crimes, it will be detrimental to the court's intention to appease people from afar."
