Narrated Salman Al-Farsi:

Allah's Apostle (p.b.u.h) said, "Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven."

Bukhari :: Book 2 :: Volume 13 :: Hadith 35

Narrated As-Saib bin Yazid:

In the life-time of the Prophet, Abu Bakr and Umar, the Adhan for the Jumua prayer used to be pronounced when the Imam sat on the pulpit. But during the Caliphate of 'Uthman when the Muslims increased in number, a third Adhan at Az-Zaura' was added. Abu 'Abdullah said, "Az-Zaura' is a place in the market of Medina."
