'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.
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا وَكِيعٌ، عَنْ مِسْعَرٍ، عَنْ هِلاَلِ بْنِ حُمَيْدٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ مَا شَبِعَ آلُ مُحَمَّدٍ صلى الله عليه وسلم يَوْمَيْنِ مِنْ خُبْزِ بُرٍّ إِلاَّ وَأَحَدُهُمَا تَمْرٌ .
