´'Abdul-Karim narrated from 'Ata', who said:` "The Messenger of Allah forbade 'Umra and Ruqba." I said: "What is Ruqba?" He said: "When one man says to another: 'This belongs to you for the rest of your life.' But if you do that, it is permissible."

Urdu marginal note:
"Until your lifetime"—this is the explanation of ‘Umra, not of Ruqba. Both of these are not good forms of gift; therefore, they have been prohibited.
