Musnad Ahmad 30:1358

Yunus narrated to us, Laith narrated to us, from Ibn ‘Ajlan, from his father, from Abu Hurayrah, from the Prophet, may Allah bless him and grant him peace, that he said: "Do you not see how Allah diverts from me the cursing and insulting of Quraysh? They insult 'Mudhammam' (the dispraised one), while I am Muhammad (the praised one)."
