Musnad Ahmad 28:225

Muhammad ibn Ja‘far narrated to us, Sa‘id narrated to us, from Yusuf, 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: "Three [types of people] attend Jumu‘ah: A man who attends it with supplication and prayer; that is a man who calls upon his Lord, if He wills He gives him, and if He wills He withholds from him. And a man who attends it with silence and listening; that is its due right. And a man who attends it and speaks vainly; that is his portion of it."
