Samura b. Jundub and al-Mughira b. Shu'ba reported God’s messenger as saying, “If anyone relates a tradition from me thinking that it is false, he is one of the liars.” Muslim transmitted it.

Hadith Takhrij´تحقيق و تخريج: محدث العصر حافظ زبير على زئي رحمه الله` «رواه مسلم (1)»
Fiqh al-Hadith: ➊ Lying is absolutely forbidden (haram), but to lie about Allah and His Messenger is a major sin (kabirah), forbidden, and according to some scholars, even disbelief (kufr). ➋ Wretched are those people who, despite this severe warning and the evidences, lie about Allah and His Messenger, write and narrate fabricated (mawdu‘) and baseless narrations. Do they not fear Allah’s punishment?! ➌ The person who narrates false traditions to people without warning them is equally a partner with the lying narrators. ◄ If in the mentioned hadith, “liars” (kadhdhibayn) is taken as dual (referring to two), then two persons are addressed in this hadith: the one who fabricates the false hadith, and the one who narrates this false hadith to people without warning them. ➍ From this severe warning, it is implicitly established that hadith is revelation (wahy) and a proof (hujjah), for the protection of which it has been clarified that the one who narrates a false hadith is a liar, and such a person will enter Hell, as is established from other authentic (sahih) ahadith. ➎ It is necessary for scholars that, when narrating hadith, they verify it, and in fact, always keep in view the knowledge of the names of narrators (‘ilm asma’ al-rijal) and the principles of hadith (usul al-hadith).

The Sunnah demonstrates the prohibition of transmitting abominable transmissions just as in the example from the Qur’ān regarding the prohibition of the report of the sinful. ¤ There is a famous narration on authority of the Messenger of Allah, peace and blessings of Allah upon him, that: ‘Whoever relates on my authority a narration while aware that it is a lie, then he is one of the liars’ . Abū Bakr ibn Abī Shaybah narrated it to us that Wakī narrated to us, on authority of Shu’bah, on authority of al-Hakam, on authority of Abd ir-Rahman ibn Abī Laylā, on authority of Samurah bin Jundab. And also Abū Bakr ibn Abī Shaybah narrated to us, that Wakī narrated to us, on authority of Shu’bah and Sufyān, on authority of Habīb, on authority of Maymūn ibn Abī Shabīb, on authority of al-Mughīrat ibn Shu’bah, they both said that the Messenger of Allah, peace and blessings of Allah upon him, said the same thing.

Hadith Commentary:Benefits and Issues: If narrating such ahadith is considered a lie, the falsehood of which is only presumed (zanni), then how can it be permissible to narrate a hadith whose attribution as marfu‘ (directly attributed to the Prophet sallallahu alayhi wa sallam) is neither known nor established, without clarifying its status?
