The importance of going to jumu'ah early.

 The importance of going to jumu'ah early. 

Alhamdulillah, going to the friday prayer is a great reward and one is rewarded if one performs the ghusl and go to the jumuah prayer at the early hour.

As reported in Hadith,

Allah's Messenger (ﷺ) (p.b.u.h) said, "Any person who takes a bath on Friday like the bath of Janaba and then goes for the prayer (in the first hour i.e. early), itis as if he had sacrificed a camel (in Allah's cause); and whoever goes in the second hour it is as if he had sacrificed a cow; and whoever goes in the third hour, then it is as if he had sacrificed a horned ram; and if one goes in the fourth hour, then it is as if he had sacrificed a hen; and whoever goes in the fifth hour then it is as if he had offered an egg. When the Imam comes out (i.e. starts delivering the Khutba), the angels present themselves to listen to the Khutba."

Sahih al-Bukhari 881.

Abu Al-Ash'ath narrated that:

He heard Aws bin Aws, the Companion of the Messenger of Allah (ﷺ) say: "The Messenger of Allah (ﷺ) said: 'Whoever performs Ghusl on Friday and washes (ghassala), and comes early to the masjid, walking not riding, andsits close to the imam and listens attentively and does not engage in idle speech, for every step he takes he will have (the reward of) a year's worth of good deeds.'"

Sunan an Nasa'i.

Book 14, Hadith 21.

Talking while Imam delivers the khutbah is a sin and nullifies the Friday prayer of the person.

As reported in hadith,

Whosoever talks while imam delivers khutbah is like a donkey carrying many books and the one that says keep quiet has no reward of the prayer.

Sahih by ibn hibban.
