Narrated Abdullah Ibn Umar; Abdullah Ibn Abbas: The Prophet (peace be upon him) said:
It is not lawful for a man to make a donation or give a gift and then take it back, except a father regarding what he gives his child. One who gives a gift and then takes it back is like a dog which eats and vomits when it is full, then returns to its vomit.
Sunan Abi Dawud, Book 24, Hadith 124
