Musnad Ahmad 1153:1854

Abu Mu'awiyah narrated to us, he said: Al-A'mash narrated to us, from Ibrahim, from Al-Aswad, from Aisha, she said: "I would often braid the garlands for the sacrificial animals of the Messenger of Allah, peace and blessings of Allah be upon him. He would then garland his sacrificial animal, and send it away. Then he would remain, not avoiding anything that the one in the state of Ihram avoids."
