Narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Whoever gives ‘Umra (a gift of property for life), it will be established for the one to whom it is given; likewise, whoever gives Ruqba (a gift of property until the death of either the giver or receiver), it will also be established for the one to whom it is given; and whoever gives something as a gift and then takes it back, he is like a man who eats his own vomit.
