Narated By Salman-Al-Farsi RA: The Prophet Peace Be Upon Him said, “Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jumua prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutba, his sins in-between the present and the last Friday would be forgiven.”
