Narrated Abu Huraira
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), it is 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."
Narrated Abu Huraira
While `Umar (bin Al-Khattab) was delivering the Khutba on a Friday, a man entered (the mosque). `Umar asked him, "What has detained you from the prayer?" The man said, "It was only that when I heard the Adhan I performed ablution (for the prayer)." On that `Umar said, "Did you not hear the Prophet saying: 'Anyone of you going out for the Jumua prayer should take a bath'?".
