The Messenger of Allah (SWAS)saw a man driving the sacrificial camel. He said ride on it. He said this is a sacrificial camel. He again said ride on it, bother you, either the second or the third time he spoke.
Sunan Abi Dawud Book 11, Hadith 40
← Previous Hadith The Messenger of Allah (SWAS) sent sacrificial camels as offering (to the Ka’bah) and I twisted with my own hands their garlands of coloured wool that we had with us. Next morning he came free from restrictions, having intercourse (with his wife) as a man not wearing Ihram does with his wife.

Sunan Abi Dawud Book 11, Hadith 39 Next Hadith → I asked Jabir bin `Abdallah about riding on the sacrificial camels. He said I heard The Messenger of Allah (SWAS) saying ride on them gently when you have nothing else till you find a mount.

Sunan Abi Dawud Book 11, Hadith 41
