(23) باب مَا كَانَ النَّبِيُّ صلى الله عليه وسلم وَأَصْحَابُهُ يَأْكُلُونَ
Narrated Abu Huraira:
Once the Prophet (ﷺ) 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.
