´Hajjaj narrated from Abu Az-Zubair, from Tawus, from Ibn 'Abbas, who said:` "The Messenger of Allah said: 'Umra (life-long gift) is permissible for the one to whom it is given, and Ruqba is permissible to the one to whom it is given, and the one who takes back his gift is like the one who goes back to his vomit.'"

´Sufyan narrated from Abu Az-Zubair, from Tawus, from Ibn 'Abbas, who said:` "'Umra and Ruqba are the same."

´(A different chain) from Sufyan, from Abu Az-Zubair, from Tawus, from Ibn 'Abbas, who said:` "Ruqba and 'Umra are not permissible; whoever is given something on the basis of 'Umra, it is his, and whoever is given something on the basis of Ruqba, it is his."

´(A different chain) from Hajjaj, from Abu Az-Zubair, from Tawus, from Ibn 'Abbas, who said:` "'Umra and Ruqba are not proper. Whoever gives something on the basis of 'Umra or Ruqba, it belongs to the one to whom he gave it on that basis, both during his lifetime and after his death." Hanzalah narrated it in Mursal form.
