Musnad Ahmad 1153:1624

Muhammad ibn Bakr narrated to us, he said: Ibn Jurayj informed us, he said: Ibn Shihab narrated to me, that ‘Urwah informed him, that ‘Aishah informed him, she said: "I used to twist the garlands for the sacrificial animals of the Messenger of Allah, peace and blessings of Allah be upon him. Then he would send them, and he would remain, and he would not avoid anything [that a person in ihram usually avoids]."
