An Nasai: Hadith 3770

"Sulaiman bin Hisham asked me about a lifelong gift. I said: 'Muhammad bin Sirin narrated that Shuraih said: "The Prophet of Allah ruled that a lifelong gift is permissible."'" Qatadah said: "I said: 'And An-Nadr bin Anas narrated to me, from Bashir bin Nahik, from Abu Hurairah, that the Prophet of Allah said: "A lifelong gift is permissible."'" Qatadah said: "I said: 'Al-Hasan used to say: "A lifelong gift is permissible."'" Qatadah said: "Az-Zuhri said: 'A lifelong gift is when it is stipulated that it is for the one to whom it is given and his descendants, but if his descendants were not mentioned then the condition is valid (and it reverts to the one who gave it).'" Qatadah said: "So 'Ata' bin Abi Rabah was asked, and he said: 'Jabir bin Abdullah narrated to me that Allah's Messenger said: "Umra is permissible."'" Qatadah said: "Az-Zuhri said: 'The Caliphs (Khulafa') did not rule according to this.'" 'Ata' said: "Abdul-Malik bin Marwan ruled according to this."
