Mishkat al-Masabih #218

Ibn ‘Abbas reported God’s messenger as saying, “Be on your guard about tradition from me, except what you know; for he who lies about me deliberately will certainly come to his abode in hell.” Tirmidhi transmitted it, and Ibn Majah transmitted it from Ibn Mas'ud and Jabir, but did not mention, “ Be on your guard about tradition from me, except what you know.”
