Musnad Ahmad 28:219

Yazid ibn Harun narrated to us, Hammam informed us, from Qatadah, from Amr ibn Shu'ayb, from his father, from his grandfather, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Eat, drink, give charity, and wear clothing, without arrogance and without extravagance." And Yazid said once: "Without extravagance and without arrogance."
