Caution in Narrating Hadith from Rasulullah (sallallahu 'alaihi wasallam)

Hazrat ‘Abdullah bin Zubair (radhiyallahu ‘anhu) narrates that he once asked his father, Hazrat Zubair (radhiyallahu ‘anhu), “Why do you not narrate the Ahaadeeth of Rasulullah (sallallahu ‘alaihi wasallam), as such-and-such Sahaabah (radhiyallahu 'anhum) narrate?” Hazrat Zubair (radhiyallahu ‘anhu) replied, “I did not leave Rasulullah (sallallahu ‘alaihi wasallam) after accepting Islam (I am thus able to narrate many Ahaadeeth). However, on one occasion, I heard Rasulullah (sallallahu ‘alaihi wasallam) mention something (due to which I fear quoting Ahaadeeth). I heard him (sallallahu ‘alaihi wasallam) say, “The one who deliberately lies against me (fabricates Ahaadeeth and attributes them to me) should prepare his abode in the Hellfire.”
