It was narrated from Abu Hurairah that:
The Messenger of Allah (ﷺ) said: "Whoever performs Ghusl as from Janabah on Friday, then comes (to the Masjid), it is as if he sacrificed a camel. Then the one who comes in the second hour, it is as if he sacrificed a cow. Then the one who comes in the third hour, it is as if he sacrificed a ram. Then the one who comes in the fourth hour, it is as if he sacrificed a chicken. Then the one who comes in the fifth hour, it is as if he sacrificed an egg. Then when the Imam comes out, the angels attend to listen to the Khutbah."
