Musnad Ahmad 32:826

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, and Hajjaj said: Shu'bah narrated to me, from Qatadah, who said: I heard Anas ibn Malik say: A Bedouin came to the Prophet, may Allah bless him and grant him peace, and said: "When is the Hour?" He said: "What have you prepared for it?" He said: "The love of Allah and His Messenger." He said: "You are with whom you love."
