"I used to forbid you to store the meat of the sacrifices for more than three days so that there would be enough for everyone. But now Allah, the mighty and sublime, has bestowed plenty upon us, so eat some, give some in charity and store some, For these days are the days of eating, drinking and remembering Allah." A man said: "O Messenger of Allah, we used to sacrifice the 'Atirah during the Jahiliyyah in Rajab; what do you command us to do?" He said: "Sacrifice to Allah, the Mighty and Sublime, whatever month it is, do good for the sake of Allah, the Mighty and Sublime, and feed (the poor)." He said: "O Messenger of Allah, we used to sacrifice the Fara' during the Jahiliyyah; what do you command us to do?" He said: "For every flock of grazing animals, feed the firstborn as you feed the rest of your flock, until it reaches an age where it could be used to carry loads, then sacrifice it, and give its meat in charity to the wayfarer, for that is good." (Using translation from Nasāʾī 4230)
عَنِ النَّبِيِّ ﷺ قَالَ «إِنِّي كُنْتُ نَهَيْتُكُمْ عَنْ لُحُومِ الْأَضَاحِيِّ فَوْقَ ثَلَاثٍ كَيْمَا يشبَعُكُمْ فَقَدْ جَاءَ اللهُ بِالْخَيْرِ فَكُلُوا وَادَّخِرُوا وَإِنَّ هَذِهِ الْأَيَّامَ أَيَّامُ أَكْلٍ وَشُرْبٍ وَذِكْرِ اللهِ» فَقَالَ رَجُلٌ إِنَّا كُنَّا نَعْتِرُ عَتِيرَةً فِي الْجَاهِلِيَّةِ فِي رَجَبٍ فَمَا تَأْمُرُنَا؟ قَالَ «اذْبَحُوا لِلَّهِ مِنْ أَيِّ شَهْرٍ مَا كَانَ وَبَرُّوا اللهَ وَأَطْعِمُوا» فَقَالَ رَجُلٌ يَا رَسُولَ اللهِ إِنَّا كُنَّا نُفَرِّعُ فَرَعًا فِي الْجَاهِلِيَّةِ فَمَا تَأْمُرُنَا؟ فَقَالَ رَسُولُ اللهِ ﷺ «فِي كُلِّ سَائِمَةٍ مِنَ الْغَنَمِ فَرَعٌ تَغْذُو غَنَمُكَ حَتَّى إِذَا اسْتَحْمَلَ ذَبَحْتَهُ وَتَصَدَّقْتَ بِلَحْمِهِ عَلَى ابْنِ السَّبِيلِ فَإِنَّ ذَلِكَ هُوَ خَيْرٌ»
