question #1 Sahih Muslim Introduction 65, Introduction, Narration 64 : What are the implications of fabricating narrations and attributing them to the Prophet in Islamic tradition?

Uthmān bin Abī Shaybah narrated to us, Jarīr narrated to us, on authority of Raqabah that ‘Abū Ja’far al-Hāshimī al-Madanī was fabricating narrations with words of truth, and they were not from the narrations of the Prophet, peace and blessings of Allah upon him, though he was transmitting them on authority of the Prophet, peace and blessings of Allah upon him.’
