Musnad Abu Ya'la al-Mawsili 148:32

Al-Abbas ibn al-Walid al-Narsi narrated to us, Yahya ibn Sa'id al-Qattan narrated to us, from Nawfal, who said: We entered upon Anas and said, "Narrate to us what you heard from the Messenger of Allah, may Allah bless him and grant him peace." He said: The Messenger of Allah, may Allah bless him and grant him peace, said: "Three things, whoever possesses them, is forbidden to the Fire, and the Fire is forbidden to him: faith in Allah, love for the sake of Allah, and that being thrown into the Fire and burning is more beloved to him than returning to disbelief."
