Sahih Bukhari Volume 7, Book 70, Hadith 5416

حَدَّثَنِي إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّهُ مَرَّ بِقَوْمٍ بَيْنَ أَيْدِيهِمْ شَاةٌ مَصْلِيَّةٌ، فَدَعَوْهُ فَأَبَى أَنْ يَأْكُلَ قَالَ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنَ الدُّنْيَا وَلَمْ يَشْبَعْ مِنَ الْخُبْزِ الشَّعِيرِ‏

Narrated By Abu Huraira : That he passed by a group of people in front of whom there was a roasted sheep. They invited him but he refused to eat and said, "Allah's Apostle left this world without satisfying his hunger even with barley bread."
