Musnad Ahmad 25:504

Ya'qub narrated to us, my father narrated to us, from Ibn Ishaq, Abdullah ibn Abi Najih narrated to me, from Mujahid ibn Jabr, from Ibn Abbas: "That the Messenger of Allah, may Allah bless him and grant him peace, had gifted the camel of Abu Jahl, which had been seized on the day of Badr, and in its nose was a ring of silver, during the year of al-Hudaybiyah among his sacrificial animals." And he said in another place: "To enrage the polytheists thereby."
