Musnad Ahmed: Hadith 2860

The Messenger of Allah (ﷺ) sacrificed one hundred camels during Hajj, of which he slaughtered sixty with his own hand and ordered that the rest be slaughtered. Then he took a piece from each camel and they were put in a pot, and he ate from it and drank its broth. And on the day of al-Hudaibiyah he slaughtered seventy, among which was the camel of Abu Jahl. When the camels were prevented from reaching the Ka’bah, they groaned as if groaning for their offspring.
