Musnad Abu Ya'la al-Mawsili 127:5

Abu Bakr ibn Abi Shaybah narrated to us, Muhammad ibn Fudayl narrated to us, from Yunus ibn Abi Ishaq, from Burayd ibn Abi Maryam, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no servant who asks for Paradise three times, except that Paradise says: 'O Allah, admit him into Paradise.' And there is no servant who seeks refuge with Allah from the Fire three times, except that the Fire says: 'O Allah, protect him from me.'"
