《资治通鉴·唐纪·唐纪二十四》
过了不久，宗楚客又让袁守一上奏说： 当时则天太后在三阳宫患病，狄仁杰上奏请求让陛下以太子身份总揽朝政，魏元忠却秘密上奏认为不合适。这说明他很久以来一直对陛下怀有二心，请陛下对他处以严刑！ 
顷之，楚客又令袁守一奏言： 则天昔在三阳宫不豫，狄仁杰奏请陛下监国，元忠密奏以为不可，此则元忠怀逆日久，请加严诛！ 
Before long, Zong Chukè had Yuan Shouyi memorialize again, saying: When Empress Wu was ill in Sanyang Palace, Di Renjie memorialized, requesting that Your Majesty, in the capacity of Crown Prince, take charge of the government. Wei Yuanzhong, however, secretly memorialized that this was not appropriate. This shows that he has harbored disloyal thoughts toward Your Majesty for a long time. I request that Your Majesty mete out severe punishment to him!
