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, "Messenger of Allah 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).  

تَضَيَّفْتُ أَبَا هُرَيْرَةَ سَبْعًا فَكَانَ هُوَ وَامْرَأَتُهُ وَخَادِمُهُ يَعْتَقِبُونَ اللَّيْلَ أَثْلاَثًا يُصَلِّي هَذَا ثُمَّ يُوقِظُ هَذَا وَسَمِعْتُهُ يَقُولُ قَسَمَ رَسُولُ اللَّهِ ﷺ بَيْنِ أَصْحَابِهِ تَمْرًا فَأَصَابَنِي سَبْعُ تَمَرَاتٍ إِحْدَاهُنَّ حَشَفَةٌ  

The Prophet ﷺ distributed dates among us, and my share was five dates, four of which were good, and one was a ,Hashafa, and I found the Hashafa the hardest for my teeth.  

عَنْ أَبِي هُرَيْرَةَ ؓ قَسَمَ النَّبِيُّ ﷺ بَيْنَنَا تَمْرًا فَأَصَابَنِي مِنْهُ خَمْسٌ أَرْبَعُ تَمَرَاتٍ وَحَشَفَةٌ ثُمَّ رَأَيْتُ الْحَشَفَةَ هِيَ أَشَدُّهُنَّ لِضِرْسِي
