An-Nu'man bin Bashir (May Allah be pleased with them) reported:
'Umar bin Al-Khattab (May Allah be pleased with him) spoke at length regarding the worldly prosperity that people had achieved and said: "I saw that the Messenger of Allah ﷺ would pass his days in hunger and could not get even degraded dates to fill his stomach".

[Muslim].

وعن النعمان بن بشير، رضي الله عنهما، قال: ذكر عمر ابن الخطاب، رضي الله عنه، ما أصاب الناس من الدنيا، فقال: لقد رأيت رسول الله، ﷺ، يظل اليوم يتلوى ما يجد من الدقل ما يملأ به بطنه. ((رواه مسلم)). الدقل بفتح الدال المهملة والقاف: ردئ التمر.
