Musnad Ahmad 30:3343

Yunus ibn Muhammad narrated to us, Muhammad ibn Hilal al-Madani narrated to us, my father narrated to us that he heard Abu Hurairah saying: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The one who goes early for Jumu'ah is like one who offers a sacrifice. So, one who offers a camel, and one who offers a cow, and one who offers a sheep, and one who offers a chicken, and one who offers an egg."
