Musannaf Ibn Abi Shayba 36:429

Muhammad ibn al-Hasan al-Asadi narrated to us, he said: Ibrahim ibn Tahman narrated to us, from Abu al-Zubayr, from Utbah, the freed slave of Ibn Abbas, from Ibn Abbas, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) arrived from al-Ta'if, he camped at al-Ji'ranah. He distributed the spoils of war there, then he performed Umrah from there. That was when two nights remained of Shawwal.
