I was a guest of Abu Huraira for seven days. Abu Huraira, his wife and his slave used to get up and
remain awake for one-third of the night by turns. Each would offer the night prayer and then awaken
the other. I heard Abu Huraira saying, "Allah's Messenger (ﷺ) distributed dates among his companions and
my share was seven dates, one of which was a Hashafa (a date which dried on the tree before it was
fully ripe).
