Musnad Ahmad 33:669

'Abd al-Samad narrated to us, Hammad narrated to us, 'Ammar narrated to us, I heard Jabir ibn 'Abd Allah saying: The Messenger of Allah (may Allah bless him and grant him peace), Abu Bakr, and 'Umar ate fresh dates and drank water. Then the Messenger of Allah (may Allah bless him and grant him peace) said: "This is from the bliss (al-na'im) that you will be asked about."
