Musnad Ahmad 1153:1869

'Abd al-Razzaq narrated to us, he said: Ma'mar narrated to us, from al-Zuhri, from 'Urwah, from 'Aishah, who said: "I used to braid the garlands for the sacrificial animals of the Prophet, peace and blessings of Allah be upon him. Then he would send them, and he would not avoid anything that the one in the state of ihram avoids."
