Sayyiduna Jabir bin Abdullah al-Ansari (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him), Abu Bakr and Umar (may Allah be pleased with them both) came to us, and we fed them fresh dates and gave them water to drink. The Messenger of Allah (peace and blessings be upon him) said: "This is part of the blessings about which you will be questioned on the Day of Resurrection."
