Musnad Ahmad 1153:1480

Yazid narrated to us, he said: Yahya ibn Sa'id informed us, from 'Abd al-Rahman ibn al-Qasim, from his father, from 'Aishah, she said: "I used to twist the garlands for the sacrificial animals (hady) of the Messenger of Allah, peace and blessings of Allah be upon him. Then he would send them, and he would not leave anything of what he used to do before that."
