Ali bin al-Husain bin 'Ali علي بن الحسين بن علي - زين العابدين · General Behavior (Kitab Al-Adab)

The Prophet (ﷺ) said: It is enough falsehood for a man to relate everything he hears. Abu Dawud said: Hafs did not mention Abu Hurairah (in his version). Abu Dawud said: No other transmitter except this old man, that is, 'Ali b. Hafs al-Mada'ini related the perfect chain of this tradition.

so he (‘Umar’) feared that he would refer to the Messenger of Allah (May peace be upon him); therefore he allowed him.

A similar report (as previous) was narrated from a man from Thaqif, from 'Urwah bin Az-Zubair, who attributed the Hadith to the Prophet (ﷺ).
