[Transmitted by Abu Dawud]
The Friday prayer in congregation is a necessary duty for every Muslim, with four exceptions; a slave, a woman, a (young) boy, and a sick person.

[Transmitted by Sahih Bukhari]
“When it is a Friday, the angels stand at the gate of the mosque and keep on writing the names of the persons coming to the mosque in succession according to their arrivals. The example of the one who enters the mosque in the earliest hour is that of one offering a camel (in sacrifice). The one coming next is like one offering a cow and then a ram and then a chicken and then an egg respectively. When the Imam comes out (for Jumua prayer) they (i.e. angels) fold their papers and listen to the Khutba.”

[Transmitted by Abu Dawud]
Friday is divided into twelve hours. Amongst them, there is an hour in which a Muslim does not ask Allah for anything but He gives it to him. So seek it in the last hour after the afternoon prayer.

[Transmitted by Abu Dawud]
He who leaves the Friday prayer (continuously) for three Friday on account of slackness, Allah will print a stamp on his heart.

[Transmitted by Sahih Muslim]
He who took a bath and then came for Jumu’ah prayer and then prayed what was fixed for him, then kept silence till the Imam finished the sermon, and then prayed along with him, his sins between that time and the next Friday would be forgiven, and even of three days more.
