《北史·列传·卷四十五》
大军归来后，宣帝想杀掉他，便假借齐王宇文宪的事讥讽他，说： 你明明知道齐王想谋反，为什么不告发？ 
及军还，帝将杀之，乃托以齐王事诮之曰： 公知齐王谋反，何以不言？ 
After the army returned victorious, Emperor Xuan wanted to have him killed, so he used the Prince of Qi, Yuwen Xian's, case to criticize him sarcastically and said: "You clearly knew that the Prince of Qi wanted to rebel, so why didn't you expose him?"
