Abu Dawud Book 2, Hadith Number 1108.

Narated By Abdullah ibn Amr ibn al-‘As : The Prophet (PBUH) said: Three types of people attend Friday prayer; One is present in a frivolous way and that is all he gets from it; another comes with a supplication, Allah may grant or refuse his request as He wishes; another is present silently and quietly with-out stepping over a Muslim or annoying anyone, and that is an atonement for his sins till the next Friday and three days more, the reason being that Allah, the Exalted, says: “He who does a good deed will have ten times as much” (vi.160).
