Musannaf Ibn Abi Shayba 13:1755

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Hisham ibn Sa’d, from Zayd ibn Aslam, from his father, he said: The Messenger of Allah (may Allah bless him and grant him peace) said: The likeness of the one who returns to his gift is like the likeness of the dog that returns to its vomit.
