Imaam Maalik bin Anas 179 AH said to Ibn Wahb,

لَمْ أَنَّهُ لَيْسَ يَسْلَمُ رَجُلٌ حَدَّثَ بِكُلِّ مَا سَمِعَ وَلاَ يَكُونُ إِمَامًا أَبَدًا وَهُوَ يُحَدِّثُ بِكُلِّ مَا سَمِعَ

“Know that a man who relates everything he hears is not safe, and he can never be an Imām, as long as he narrates everything he hears.”
