The Ruling on Taking Back a Gift, Even by Purchasing It

Question:
The questioner asks: Is it forbidden to purchase a gift just as it is forbidden to purchase a charity? And if the recipient returns the gift to me by giving me a gift, by inheritance, or by charity, is it permissible for me to accept it?

Answer:
Taking back a gift is not permissible. The Messenger of Allah (peace and blessings be upon him) said: Even if he buys it from him, it is not permissible to take it back, even by purchase. This is because 'Umar (may Allah be pleased with him) gave a man a horse.
to fight in the cause of Allah. The man who received it did not treat the horse well; he was lazy and neglected the horse's rights. So 'Umar wanted to buy it back. He went to the Messenger of Allah (peace and blessings be upon him). Look, the Companions did not proceed with anything until they asked the Messenger of Allah (peace and blessings be upon him). Likewise, no one else should proceed with anything while ignorant without asking the scholars. So he went to the Messenger of Allah (peace and blessings be upon him) and informed him that he had given a man a horse to ride in the cause of Allah, and that the man had neglected it. Is it permissible to buy it back from him? He said: No, do not take back your gift, even if he sells it to you for a dirham. Do not take back your gift. Indeed, the one who takes back his gift is like a dog that vomits and then returns to its vomit. Yes.
