Anas bin Malik reported,

The Messenger of Allah ﷺ said, "Rise to a paradise as wide as the heavens and the earth."Umayr bin al-Humam al-Ansari asked, "Messenger of Allah, a paradise as wide as the heavens and the earth?"He replied, "Yes."Umayr exclaimed, "Excellent, excellent!"The Messenger of Allah ﷺ asked, "What makes you say, 'Excellent, excellent'?"Umayr answered, "Nothing, by Allah, Messenger of Allah, except the hope that I might be among its people."He said, "You are indeed among its people."Umayr then took out some dates from his quiver and began to eat them. Then he said, "If I were to live long enough to finish eating these dates of mine, that would be a long life indeed."So he threw away the dates he had with him, then fought them until he was killed.
