Musnad Ahmad 908:4

Ya'qub narrated to us, my father narrated to us, from Salih. Ibn Shihab said: Abdullah bin al-Harith bin Nawfal informed me, from Abdullah bin Khabbab bin al-Aratt, that Khabbab said: I watched the Messenger of Allah, may Allah bless him and grant him peace, during a prayer he performed until it was near dawn. When the Messenger of Allah, may Allah bless him and grant him peace, finished his prayer with the taslim, Khabbab came to him and said: "O Messenger of Allah, may my father and mother be sacrificed for you, you have prayed..." and he mentioned the like of Shu'ayb's hadith.
