Musnad Ahmad 1153:1447

'Abd al-Rahman narrated to us, he said: Malik narrated to us, from 'Abdullah ibn Abi Bakr, from 'Amrah bint 'Abd al-Rahman, from 'Aishah, who said: "I used to twist the garlands for the sacrificial animals of the Messenger of Allah, peace and blessings of Allah be upon him, with my hands. Then the Messenger of Allah, peace and blessings of Allah be upon him, would garland them with his own hands. Then he would send them with my father, and he would not refrain from anything that Allah, the Mighty and Majestic, had made lawful for him until the sacrificial animals were slaughtered."
