Musnad Abu Ya'la al-Mawsili 118:62

Ishaq narrated to us, Sufyan narrated to us, from al-Zuhri, who heard Anas saying: A man asked the Prophet (peace and blessings of Allah be upon him) about the Hour. He said: "What have you prepared for it?" He said: It was as if he did not mention much, except that I love Allah and His Messenger. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Then you are with whom you love."
