Sahih al-Bukhari, Volume 7, Book 65, Hadith 343 (USC-MSA) ⓘ

Narrated Abu Huraira: I used to accompany Allah's Messenger to fill my stomach; and that was when I did not eat baked bread, nor wear silk. Neither a male nor a female slave used to serve me, and I used to bind stones over my belly and ask somebody to recite a Qur'anic Verse for me though I knew it, so that he might take me to his house and feed me. Ja`far bin Abi Talib was very kind to the poor, and he used to take us and feed us with what ever was available in his house, (and if nothing was available), he used to give us the empty (honey or butter) skin which we would tear and lick whatever was in it.

حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ شَيْبَةَ، قَالَ أَخْبَرَنِي ابْنُ أَبِي الْفُدَيْكِ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كُنْتُ أَلْزَمُ النَّبِيَّ صلى الله عليه وسلم لِشِبَعِ بَطْنِي حِينَ لاَ آكُلُ الْخَمِيرَ، وَلاَ أَلْبَسُ الْحَرِيرَ، وَلاَ يَخْدُمُنِي فُلاَنٌ وَلاَ فُلاَنَةُ، وَأُلْصِقُ بَطْنِي بِالْحَصْبَاءِ، وَأَسْتَقْرِئُ الرَّجُلَ الآيَةَ وَهْىَ مَعِي كَىْ يَنْقَلِبَ بِي فَيُطْعِمَنِي، وَخَيْرُ النَّاسِ لِلْمَسَاكِينِ جَعْفَرُ بْنُ أَبِي طَالِبٍ، يَنْقَلِبُ بِنَا فَيُطْعِمُنَا مَا كَانَ فِي بَيْتِهِ، حَتَّى إِنْ كَانَ لَيُخْرِجُ إِلَيْنَا الْعُكَّةَ لَيْسَ فِيهَا شَىْءٌ، فَنَشْتَقُّهَا فَنَلْعَقُ مَا فِيهَا‏.‏
