I've tried to look for it, but I know the one you're talking about. From what I understand, Submitters rely on Quran 45:6 as well.
Book 042, Number 7147:
Abu Sa'id Khudri reported that Allah's Messenger (may peace be upon him) said: Do not take down anything from me, and he who took down anything from me except the Qur'an, he should efface that and narrate from me, for there is no harm in it and he who attributed any falsehood to me-and Hammam said: I think he also said:" deliberately" -he should in fact find his abode in the Hell-Fire.
I read also about reports of one of the Rashidoon Khalifa (I think Omar) that he was particularly harsh on people who write or report hadeeth.
