Sahih Bukhari Volume 7, Book 70, Hadith 5413

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ عَبَّاسٍ الْجُرَيْرِيِّ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَسَمَ النَّبِيُّ صلى الله عليه وسلم يَوْمًا بَيْنَ أَصْحَابِهِ تَمْرًا، فَأَعْطَى كُلَّ إِنْسَانٍ سَبْعَ تَمَرَاتٍ، فَأَعْطَانِي سَبْعَ تَمَرَاتٍ إِحْدَاهُنَّ حَشَفَةٌ، فَلَمْ يَكُنْ فِيهِنَّ تَمْرَةٌ أَعْجَبَ إِلَىَّ مِنْهَا، شَدَّتْ فِي مَضَاغِي‏.‏

Narrated By Abu Huraira : Once the Prophet distributed dates among his companions and gave each one seven dates. He gave me seven dates too, one of which was dry and hard, but none of the other dates was more liked by me than that one, for it prolonged my chewing it.
