The Book Pertaining to Piety and Softening of Hearts (Kitab Al-Zuhd wa Al-Raqa'iq)
Muslim :: Book 42 : Hadith 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.
