《元史·列传·卷五十》
其后有人向朝廷诬告德辉受鬼国千匹马的贿赂，世祖说： 此人朕所素知，虽一羊也不随便接收，哪有受鬼国贿赂的事！ 
其后有以受鬼国马千数谮德辉于朝者，帝曰： 是人朕所素知，虽一羊不妄受，宁有是耶！ 
Afterward, someone made false accusations to the court, saying that Dehui had accepted a bribe of a thousand horses from the Luoshigan Kingdom, but the Shizu said, “I know this man well. He would not even casually accept a sheep, so how could he possibly have accepted a bribe from the Luoshigan Kingdom?”
