´It was narrated that Zaid bin Thabit said:` The Messenger of Allah said: "Whoever gives a life-long gift, it belongs to the one to whom he gave it, both during his life and after his death. And do not give things on the basis of Ruqba, for whoever is given something on the basis of Ruqba, it becomes part of his estate."

Benefits and Issues:
Whatever is given to someone for a lifetime will not return to the giver after the recipient’s death; rather, just as the rest of the deceased’s estate is distributed among his heirs, so too will the thing received in this manner be included in the inheritance and divided among his heirs. This is because, according to the Shariah, this item falls under the ruling of a gift (hiba), and therefore it will be considered the lawful property of the recipient.

That is, in the event of the death of the one to whom the ‘umra was given, it will go to his heirs; it will not return to the giver.
