The final Messenger of Allah (Sallallaahu Alayhi Wasallam) said,
“The angels sit at the doors of the Masjids and with them are scrolls in which they record the people (who come in). When the Imam appears, the scrolls are rolled up.”
Abu Umamah was asked,
“Does the one who comes after the Imam still have a Friday Prayer?”
He (Sallallaahu Alayhi Wasallam) said,
“Certainly, but he is not one of those who is recorded (as coming early).”

Narrated by Salman-Al-Farsi (radiallaahu anhu), The Prophet (Sallallaahu `alayhi wa sallam) 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.”

The Prophet (Sallallaahu `alayhi wa sallam) said,
“There is no time on Friday at which no Muslim would stand, pray and beg Allah for what is good but He would give it to him”
