Tirmidhi

Narrated from Abdullah bin Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The example of a person who gives a gift and then takes it back is like a dog that keeps eating until it is full, then vomits, and then licks it up again." © Imam Tirmidhi says:
There are also ahadith on this subject from Ibn Abbas and Abdullah bin Amr (may Allah be pleased with them all).

‘Abdullah bin ‘Umar and ‘Abdullah bin ‘Abbas (may Allah be pleased with them) narrated that the Prophet (peace and blessings of Allah be upon him) said: “It is not permissible for a man to give a gift and then take it back, except for a father who gives something to his son (he may take it back). And whoever gives a gift and then takes it back is like a dog that eats until it is full, then vomits, and then eats its vomit.” __REF_N__ Imam Tirmidhi says:
1- This hadith is hasan sahih.
2- Shafi’i says: It is not permissible for the giver of a gift to take it back except for a father, because it is permissible for him to take back what he has given to his son. He has deduced this from this hadith.
