Musannaf Ibn Abi Shayba 8:2148

Abu Bakr narrated to us, he said: Isma'il ibn 'Ayyash narrated to us, from Sa'id ibn Yusuf, from Yahya ibn Abi Kathir, from 'Ikrimah, the freed slave of Ibn 'Abbas, who said: The Messenger of Allah (may Allah bless him and grant him peace) performed 'Umrah from al-Tan'im while he was in the state of Ihram.
