Ash-Shama'il Al-Muhammadiyah, Book 50, Hadith 351 (English)

Nu'maan ibn Bashir Radiyallahu 'Anhu says: "Are you not in the luxuries of eating and drinking, whereas, I had observed that Rasulullah Sallallahu 'Alayhi Wasallam did not possess ordinary types of dates to fill his stomach".

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ‏:‏ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ‏:‏ سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ، يَقُولُ‏:‏ أَلَسْتُمْ فِي طَعَامٍ وَشَرَابٍ مَا شِئِتُمْ‏؟‏ لَقَدْ رَأَيْتُ نَبِيَّكُمْ صلى الله عليه وسلم، وَمَا يَجِدُ مِنَ الدَّقَلِ، مَا يَمْلأُ بَطْنَهُ‏.‏
