Yahya related to me from Malik from Abu'z Zinad from al-Araj fromAbu Hurayra that the Messenger of Allah, may Allah bless him and granthim peace, saw a man driving forward a camel which he was going tosacrifice, and he told him to ride it. The man said, "Messenger ofAllah, it is an animal that I am going to sacrifice," and he replied,"Ride it, woe on you," either the second or the third time. (RU)
