Allah's Messenger (ﷺ) said: "Whoever takes a bath, then comes to al-Jumu'ah prayer, then prays what was fixed for him, then keeps silent till the Imam finishes the Khutbah (religious talk - sermon), and then prays along with him - his sins (committed) between that time and the next Friday will be forgiven, with an addition of three days more."[Reported by Muslim].
