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'".
