Musnad Abu Ya'la al-Mawsili 108:23

Ibrahim narrated to us, Hammad narrated to us, from Ammar bin Abi Ammar, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him), Abu Bakr, and Umar came to us. We fed them fresh dates and gave them water to drink. The Messenger of Allah (peace and blessings of Allah be upon him) said: "This is from the bliss (al-na'im) that you will be asked about."
