Sahih Muslim Book - 35, Hadith - 5109

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ ، أَخْبَرَنَا أَبُو عَاصِمٍ ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ ، أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: مَنْ ضَحَّى مِنْكُمْ فَلاَ يُصْبِحَنَّ فِي بَيْتِهِ بَعْدَ ثَالِثَةٍ شَيْئًا ، فَلَمَّا كَانَ فِي الْعَامِ الْمُقْبِلِ ، قَالُوا: يَا رَسُولَ اللهِ ، نَفْعَلُ كَمَا فَعَلْنَا عَامَ أَوَّلَ ، فَقَالَ: لاَ ، إِنَّ ذَاكَ عَامٌ كَانَ النَّاسُ فِيهِ بِجَهْدٍ ، فَأَرَدْتُ أَنْ يَفْشُوَ فِيهِمْ.

It was narrated from Salamah bin Al-Akwa' that the Messenger of Allah (s.a.w) said: "Whoever among you offers a sacrifice, nothing of it should be left in his house after the third day." The following year, they said: "O Messenger of Allah, shall we do what we did last year?" He said: "No, that was a year when people were hard-pressed, and I wanted (the meat) to be distributed among them."
