Musnad Ahmad 128:4

Waki’ narrated to us, Shu’bah narrated to us, from Mu’awiyah ibn Qurrah, from his father: A man used to come to the Prophet, may Allah bless him and grant him peace, and with him was a son of his. The Prophet, may Allah bless him and grant him peace, said to him, "Do you love him?" He said, "O Messenger of Allah, may Allah love you as I love him." Then the Prophet, may Allah bless him and grant him peace, missed him and said, "What happened to the son of so-and-so?" They said, "O Messenger of Allah, he has died." The Prophet, may Allah bless him and grant him peace, said to his father, "Would you not love that you do not come to any of the gates of Paradise except that you find him waiting for you?" A man said, "O Messenger of Allah, is this specifically for him, or for all of us?" He said, "Rather, for all of you."
