It was narrated that Ibn 'Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) said:

“A life-long gift[1] belongs to the one to whom it is given, and a gift given to the last one (of the giver or recipient) who remains alive[2] belongs to the one to whom it was given, and the one who takes back his gift is like the one who goes back to his vomit."
