Sayyiduna Abu Qirsafah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Narrate from me what you hear, and it is not lawful for any man to lie about me. Whoever lies about me - that is, says about me what I did not say - a house will be built for him in Hell in which he will graze."
