حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " مَنْ ضَحَّى مِنْكُمْ فَلاَ يُصْبِحَنَّ بَعْدَ ثَالِثَةٍ وَفِي بَيْتِهِ مِنْهُ شَىْءٌ ". فَلَمَّا كَانَ الْعَامُ الْمُقْبِلُ قَالُوا يَا رَسُولَ اللَّهِ نَفْعَلُ كَمَا فَعَلْنَا عَامَ الْمَاضِي قَالَ " كُلُوا وَأَطْعِمُوا وَادَّخِرُوا فَإِنَّ ذَلِكَ الْعَامَ كَانَ بِالنَّاسِ جَهْدٌ فَأَرَدْتُ أَنْ تُعِينُوا فِيهَا ".
