Al-Lu'lu Wal-Marjan 493 — The Book of Jumu'a (Friday)

Abu Hurairah Narrated from:

Allâh's Messenger صلى الله عليه وسلم said, "Any person who takes a bath on Friday like the bath of Janâba and then goes for the Salât (prayer) (in the first hour i.e. early), it is as if he had sacrificed a camel (in Allâh'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 Imâm comes out [i.e. starts delivering the Khutba (religious talk)], the angels present themselves to listen to the Khutba." ( Sahih Al-Bukhari, Hadith No. 6, Vol. 2)
