Musnad Ahmad 27:1985

'Abdullah ibn al-Walid narrated to us, Sufyan narrated to us, Jahdam narrated to me, from 'Abdullah ibn Badr, from Ibn 'Umar, who said: "We went out with the Prophet, may Allah bless him and grant him peace, and we did not exit the state of ihram. And [we went out] with Abu Bakr, and 'Umar, and 'Uthman, and they did not exit the state of ihram."
