An Nasai

"My father narrated to us: Ubaidullah -he is, Ibn 'Amr- narrated to us, from Sufyan, from Ibn Abi Najih, from Tawus, from Zaid bin Thabit, that the Prophet said: 'Ar-Ruqba is permissible.'"

"Muhammad -he is, Ibn Yusuf- narrated to us, he said: 'Sufyan narrated to us from Ibn Abi Najih, from Tawus, from a man, from Zaid bin Thabit that the Prophet ruled that the Ruqba belongs to the one to whom it is given.'"

"Abdul-Jabbar bin Al-'Ala' narrated to us, he said: 'Sufyan narrated to us from Ibn Abi Najih, from Tawus, and perhaps it is from Ibn 'Abbas, who said: There is no Ruqba, and whoever gives a gift on the basis of Ruqba, it is part of his estate.'"

"Do not give away your property on the basis of Ruqba, for whoever gives a gift on that basis, it belongs to the one to whom he gave it."

"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.'"

"'Umra and Ruqba are the same."

"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."

"'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.
