Musannaf Ibn Abi Shayba 13:1752

Abu Bakr narrated to us, he said: Ibn ‘Ulayyah narrated to us, from Ayyub, from ‘Ikrimah, from Ibn ‘Abbas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "We do not have an evil example. The one who takes back his gift is like the dog that returns to its vomit."
