Musnad Ahmad 32:2015

Rawh narrated to us, Shu'bah narrated to us, Qatadah narrated to us, from Anas ibn Malik, from the Prophet (peace and blessings of Allah be upon him), who said: "None of you believes until Allah and His Messenger are more beloved to him than anything else, and until being cast into the fire is more beloved to him than returning to disbelief after Allah has saved him from it. And none of you believes until I am more beloved to him than his child, his father, and all of mankind."
