TIME OF AUSTERITY H H 474 "Omar, the son of Khattab reminded the people of the austere life Muslims once led before they became rich and prosperous (during his caliphate) and said: 'I have known the Prophet, praise and peace be upon him, pass days in hunger. Even days when he was unable to get some rotten dates to satisfy his hunger.'" R 474 Muslim with a chain up to Nu'man, the son of Bashir who related this.
472- وعن النعمان بن بشير رضي الله عنهما ، قَالَ : ذَكَرَ عُمَرُ بْنُ الخَطَّابِ رضي الله عنه ، مَا أَصَابَ النَّاسُ مِنَ الدُّنْيَا ، فَقَالَ : لَقَدْ رَأيْتُ رسول الله صلى الله عليه وآله وسلم يَظَلُّ الْيَوْمَ يَلْتَوِي مَا يَجِدُ مِنَ الدَّقَلِ مَا يَمْلأ بِهِ بَطْنَهُ . رواه مسلم . " الدَّقَلُ" بفتح الدَّال المهملة والقاف : رديءُ التمرِ .
