Musnad Ahmad 1153:1365

Muhammad ibn Ja‘far narrated to us, he said: Sa‘id narrated to us, from Abu Ma‘shar, from al-Nakha‘i, from al-Aswad ibn Yazid, that ‘Aishah said: "The Messenger of Allah (peace and blessings of Allah be upon him) used to send the sacrificial animals (al-hady), and we would twist their garlands for them. Then, he would not refrain from anything that the one in the state of ihram refrains from."
