حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ الدُّنْيَا سِجْنُ الْمُؤْمِنِ وَجَنَّةُ الْكَافِرِ ‏"‏ ‏.‏
Translation
'A'isha reported

Never could the family of Muhammad (ﷺ) (afford to eat) the bread of wheat for two days successively. Even (out of these two days) one (was such wherein he could get) only a date.
