Musannaf Ibn Abi Shayba 21:688

Muhammad ibn Fudayl narrated to us, from Yunus ibn ‘Amr, from Burayd ibn Abi Maryam, from Anas ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no servant who asks Allah for Paradise three times, except that the Fire says: 'O Allah, protect him from me.'"
