Musnad Ahmad 25:1021

Yahya ibn Adam narrated to us, Zuhayr narrated to us, from Muhammad ibn Abd al-Rahman ibn Abi Layla, from al-Hakam, from Miqsam, from Ibn Abbas, who said: "The Messenger of Allah, peace and blessings of Allah be upon him, slaughtered one hundred camels during the Hajj. He slaughtered sixty of them with his own hand, and he commanded the remainder, so they were slaughtered. He took a piece of meat from every camel, and they were gathered in a pot, so he ate from it and sipped from its broth. He slaughtered seventy on the day of al-Hudaybiyah, among which was the camel of Abu Jahl. When they were prevented from reaching the House (the Kaaba), it (the camel) groaned just as it groans for its young."
