Musnad Ahmad 1153:511

Hashim narrated to us, Layth narrated to us, he said: Ibn Shihab narrated to me, from Urwah ibn al-Zubayr and Amrah bint Abd al-Rahman, that Aisha, the wife of the Prophet, may God bless him and grant him peace, said: "The Messenger of God, may God bless him and grant him peace, used to send [animals for] sacrifice from Medina, and I would twist the garlands for his sacrificial animals. Then, he would not avoid anything that the one in the state of ihram avoids."
