Mishkat al-Masabih, hadith 2532

عَنْ سَلَمَةَ بْنِ الْأَكْوَعِ قَالَ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ «مَنْ ضَحَّى مِنْكُمْ فَلَا يُصْبِحَنَّ بَعْدَ ثَالِثَةٍ وَفِي بَيْتِهِ مِنْهُ شَيْءٌ» . فَلَمَّا كَانَ الْعَامُ الْمُقْبِلُ قَالُوا: يَا رَسُولَ اللَّهِ نَفْعَلُ كَمَا فَعَلْنَا الْعَامَ الْمَاضِي؟ قَالَ: «كُلُوا وَأَطْعِمُوا وَادَّخِرُوا فَإِنَّ ذَلِكَ الْعَامَ كَانَ بِالنَّاسِ جَهْدٌ فَأَرَدْتُ أَنْ تُعِينُوا فِيهِمْ»

Salama b. al-Akwa‘ reported the Prophet as saying, “Those of you who make a sacrifice must not have any of it in their house after three days." The following year the people asked him whether they should do as they had done the previous year, and he said, “Eat, provide food for others, and store some up, for that year there was distress among the people and I wanted you to help them." Bukhari and Muslim.
