Musnad Abu Ya'la al-Mawsili 150:148

'Abd al-A'la narrated to us, Shuja' ibn al-Walid narrated to us, from Muhammad ibn 'Amr, from Yahya ibn 'Abd al-Rahman, from 'Aisha, who said: We went out with the Messenger of Allah (may Allah bless him and grant him peace) in three types. Among us were those who entered into the state of ihram for Hajj and 'Umrah together, among us were those who entered into the state of ihram for Hajj alone, and among us were those who entered into the state of ihram for 'Umrah alone. Whoever entered into the state of ihram for Hajj and 'Umrah together did not exit from anything that was forbidden to him until he completed the rites of Hajj. Whoever entered into the state of ihram for Hajj alone did not exit from anything that was forbidden to him until he completed the rites of Hajj. Whoever entered into the state of ihram for 'Umrah alone performed the circumambulation (tawaf) of the House and performed the sa'i between al-Safa and al-Marwah, then he exited from what was forbidden to him until he began Hajj.
