English translation
3559. It was narrated that Zaid bin Thābit said: "The Messenger of Allāh ﷺ said: 'Whoever gives something as a life-long gift, it belongs to the one to whom it is given, during his life and after his death. And do not give gifts to be given to the last one alive; if someone is given such a gift, it is to be regarded as part of his estate.'" (Sahih)
