The Messenger of Allah (SWAS) offered the noon prayer at Dhu al-Hulaifah. He then sent for a camel and made incision in the right side of its hump ; he then took out the blood by pressing it and tied two shoes in its neck. He then rode on his mount (camel) and reached al-Baida, he raised his voice for the talbiyah for performing Hajj.
Sunan Abi Dawud Book 11, Hadith 32
