Jumu'a
Section: Doing Ghusl on the Day of Jumua
Book 5, Number 5.1.1:
Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman, from Abu Salih as-Sammani from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "If someone does ghusl for major ritual impurity on the day of jumua and then goes in the first part of the time, it is as if he had offered up a camel. If he goes in the second part of the time, it is as if he had offered up a cow.
