Musnad Ahmad 30:3828

'Ali ibn Thabit narrated to us, Ja'far narrated to me, from Yazid ibn al-Asamm, who said: It was said to Abu Hurayrah, "You have narrated too much, you have narrated too much." He said: "If I were to narrate to you everything that I heard from the Prophet, may Allah bless him and grant him peace, you would pelt me with dung and you would not look at me."
