《资治通鉴·唐纪·唐纪二十四》
唐中宗对杨再思等人道： 魏元忠为朝廷效力多年，朕因而对他特意从轻发落，现在制命已经颁行，哪里能够屡次更改！
上谓再思等曰： 元忠驱使日久，朕特矜容，制命已行，岂宜数改！
Tang Zhongzong said to Yang Zaisi and the others: Wei Yuanzhong has served the court for many years. I therefore specially treated him leniently. The edict has now been issued, so how can it be repeatedly changed?
