Nofal bin lyaas Al Hadhali Radiyallahu 'Anhu says:
"'Abdurrahmaan bin'Awf Radiyallahu'Anhu (who is a Sahaabi from among the 'Ashrah Mubash-sharah) was an associate of ours, and verily he was the best associate. Once we were returning from a place with him. On returning we went with him to his house. When he went home he first took a bath. After he had taken a bath, bread and meat was brought in a big utensil. Upon seeing this 'Abdurrahmaan Radiyallahu 'Anhu began to cry. I asked: 'What happened, why are you crying?'. He began saying: 'Till the demise of Rasulullah Sallallahu 'Alayhi Wasallam, nor did he, nor his family members ever fill their stomachs even if it was only with bread that was made of barley. Now after Rasulullah Sallallahu'Alayhi Wasallam, as far as I can think, this wealthy status of ours is not for any good'.
