Musnad Ahmad 32:1977

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Qatadah, Anas ibn Malik narrated to us, that the Messenger of Allah, may Allah bless him and grant him peace, used to say: "O Allah, the life is the life of the Hereafter." And Shu‘bah said: Or he said: "O Allah, there is no life except the life of the Hereafter, so honor the Ansar and the Muhajirun."
