Ibn Abi al-Zinad (may Allah have mercy on him) narrates from his father, and he from the jurists of Madinah, that they used to say that every gift given by a person of means carries no compensation and no return; and they said: The return is for the one who gives his gift for the sake of a return; he has the greater right to his gift as long as he has not been given a return for it. Umar bin Abd al-Aziz (may Allah have mercy on him) ruled likewise.
In the narration of Isa bin Mina: He has the greater right to his gift as long as he has not been given a return for it and as long as it has not perished.
