Sunan an-Nasa'i 4431
It was narrated that 'Aishah said:
" "Some Bedouins came to Al-Madinah at the time of (Eid) Al-Adha and the Messenger of Allah said: 'Eat, and store (the meat) for three days.' After that they said: 'O Messenger of Allah, the people used to benefit form their sacrifices by melting down the fat, and (also) making water skins from them.' He said: 'Why are you asking?' He said: 'Because you forbade us form keeping the meat of the sacrificial animals.' He said: 'I only forbade that because of the Bedouins who came. (Now) eat it, store it and give it in charity," (Sahih )
أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ مَالِكٍ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي بَكْرٍ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، قَالَتْ دَفَّتْ دَافَّةٌ مِنْ أَهْلِ الْبَادِيَةِ حَضْرَةَ الأَضْحَى فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ كُلُوا وَادَّخِرُوا ثَلاَثًا ‏"‏ ‏.‏ فَلَمَّا كَانَ بَعْدَ ذَلِكَ قَالُوا يَا رَسُولَ اللَّهِ إِنَّ النَّاسَ كَانُوا يَنْتَفِعُونَ مِنْ أَضَاحِيهِمْ يَجْمِلُونَ مِنْهَا الْوَدَكَ وَيَتَّخِذُونَ مِنْهَا الأَسْقِيَةَ ‏.‏ قَالَ ‏"‏ وَمَا ذَاكَ ‏"‏ ‏.‏ قَالَ الَّذِي نَهَيْتَ مِنْ إِمْسَاكِ لُحُومِ الأَضَاحِي ‏.‏ قَالَ ‏"‏ إِنَّمَا نَهَيْتُ لِلدَّافَّةِ الَّتِي دَفَّتْ كُلُوا وَادَّخِرُوا وَتَصَدَّقُوا ‏"‏ ‏.‏
