I heard an-Nuʿman - i.e., bin Basheer - say: ʿUmar ؓ mentioned what the people had acquired of worldly gains and said: I saw the Messenger of Allah ﷺ remaining curled up [with hunger pangs] all day, unable to find even the worst type of dates with which to fill his stomach.
لَقَدْ رَأَيْتُ رَسُولَ اللهِ ﷺ يَظَلُّ الْيَوْمَ يَلْتَوِي مَا يَجِدُ دَقَلًا يَمْلَأُ بِهِ بَطْنَهُ
