Musnad Abu Ya'la al-Mawsili 150:349

Muhammad ibn al-Muthanna narrated to us, Uthman ibn Umar narrated to us, Malik narrated to us, from Abdullah ibn Abi Bakr, from Amrah, from Aisha, that she said: The Messenger of Allah (ﷺ) garlanded his sacrificial animal and marked it, and he sent it with Abu Bakr. Then he did not refrain from anything that Allah had made lawful for him until he slaughtered the sacrificial animal.
