He who sacrifices (animal) among you nothing should be left in his house (out of its flesh) on the morning of the third day. When it was the next year they (his Companions) said: Should we do this year as we did daring the previous year? Thereupon he said: Don't do that, for that was a year when the people were hard pressed (on account of poverty). so I wanted that the (flesh) might be distributed amongst them.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ ضَحَّى مِنْكُمْ فَلاَ يُصْبِحَنَّ فِي بَيْتِهِ بَعْدَ ثَالِثَةٍ شَيْئًا فَلَمَّا كَانَ فِي الْعَامِ الْمُقْبِلِ قَالُوا يَا رَسُولَ اللَّهِ نَفْعَلُ كَمَا فَعَلْنَا عَامَ أَوَّلَ فَقَالَ لاَ إِنَّ ذَاكَ عَامٌ كَانَ النَّاسُ فِيهِ بِجَهْدٍ فَأَرَدْتُ أَنْ يَفْشُوَ فِيهِمْ  

[Machine] The Messenger of Allah ﷺ said on the day of Eid al-Adha, "Whoever makes a sacrifice from among you, let him not partake in anything from his sacrifice before the third day in his home." So when the following year's Eid al-Adha was near, they asked the Messenger of Allah, "O Messenger of Allah, should we do the same as we did last year?" He said, "No, people were making an effort, so I wanted to provide assistance. Eat, feed others, and save some."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَوْمَ الْأَضْحَى «مَنْ ضَحَّى مِنْكُمْ فَلَا يُصْبِحْ بَعْدَ ثَالِثَةٍ فِي بَيْتِهِ شَيْءٌ مِنْ أُضْحِيَتِهِ» فَلَمَّا كَانَ الْعَامُ الْمُقْبِلُ يَوْمَ الْأَضْحَى قَالُوا يَا رَسُولَ اللَّهِ نَفْعَلُ فِي هَذَا كَمَا فَعَلْنَا فِي الْعَامِ الْمَاضِي؟ قَالَ «لَا كَانَ النَّاسُ بِجَهْدٍ فَأَرَدْتُ أَنْ تُعِينُوا فِيهَا كُلُوا وَأَطْعِمُوا وَادَّخِرُوا»
