Ash-Shama'il Al-Muhammadiyah, Book 46, Hadith 316 (English) ⓘ

Anas Radiyallahu 'Anhu reports: ''Rasulullah Sallallahu 'Alayhi Wasallam accepted and attended invitations where bread made of barley, and stale fat a few days old was served (Without hesitation he accepted these invitations). Rasulullah Sallallahu 'Alayhi Wasallam had pawned his armour to a Jew. Till the end of his life Rasulullah Sallallahu 'Alayhi Wasallam did not possess a sufficient amount to release that armour'".

حَدَّثَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى الْكُوفِيُّ، قَالَ‏:‏ حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنِ الأَعْمَشِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم، يُدْعَى إِلَى خُبْزِ الشَّعِيرِ، وَالإِهَالَةِ السَّنِخَةِ، فَيُجِيبُ وَلَقَدْ كَانَ لَهُ دِرْعٌ عِنْدَ يَهُودِيٍّ، فَمَا وَجَدَ مَا يَفُكُّهَا حَتَّى مَاتَ‏.‏
