Sayyiduna Abdullah bin Zubair (may Allah be pleased with them both) says that I asked my father, Sayyiduna Zubair (may Allah be pleased with him), "Why do you not narrate the hadiths of the Prophet (peace and blessings be upon him)?" He replied, "Since I accepted Islam, I have never been separated from the Prophet (peace and blessings be upon him), but I heard the Prophet (peace and blessings be upon him) say: 'Whoever deliberately attributes a false statement to me, he should make his abode in the Hellfire.'" (That is why I am afraid.)
