Musnad Ahmad 285:3

Muhammad ibn Ja‘far narrated to us, he said: Shu‘bah narrated to us, from Mughirah, from Abu Wa’il, from Qays ibn Abi Gharzah, who said: The Messenger of Allah (may Allah bless him and grant him peace) came to us while we were in the marketplace and said: "Indeed, this marketplace is intermingled with idle talk and swearing, so mix it with charity."
