Sahih Muslim Book 7, Hadith Number 3048.

Chapter : It is permissible to ride the sacrificial animal (camel) for one who is in need of it.

Hammam b. Munabbih reported: It is one out of these (narrations) that Abu Huraira (Allah be pleased with him) narrated to us from Muhammad the Messenger of Allah (may peace be upon him), and he narrated to us traditions out of which is that he said: When there was a person who was driving a garlanded sacrificial camel, Allah’s Messenger (may peace be upon him) said to him: Woe to you; ride on it. He said: Messenger of Allah, it is a sacrificial animal, whereupon Allah’s Messenger (may peace be upon him) said: Woe to you, ride on it; woe to you, ride on it.
