"It was said to the prophet: 'During the Jahiliyyah we used to offer the 'Atirah.' He said: 'Slaughter for the sake of Allah, the Mighty and sublime, no matter what month it is; do good for the sake of Allah, the Mighty and sublime, and feed the poor."' (Using translation from Nasāʾī 4228)   

ذَكَرَ النَّبِيَّ ﷺ قَالَ كُنَّا نَعْتِرُ فِي الْجَاهِلِيَّةِ قَالَ اذْبَحُوا لِلَّهِ فِي أَيِّ شَهْرٍ مَا كَانَ وَبَرُّوا اللهَ وَأَطْعِمُوا  

“A man called the Messenger of Allah ﷺ and said: ‘O Messenger of Allah, we used to sacrifice the ‘Atirah during the Ignorance days in Rajab,; what do you command us to do?’ He said: “Sacrifice to Allah whatever month it is, do good for the sake of Allah and feed (the poor).’ They said: ‘O Messenger of Allah, we used to sacrifice the Far’ah during the Ignorance days; what do you command us to do?’ He said: ‘For every Sa’imah* (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’ – I** think he said – ‘to the wayfarer, for that is good.’” (Using translation from Ibn Mājah 3167)   

يَا رَسُولَ اللهِ إِنَّا كُنَّا نَعْتِرُ عَتِيرَةً فِي الْجَاهِلِيَّةِ فِي رَجَبٍ فَمَا تَأْمُرُنَا يَا رَسُولَ اللهِ؟ قَالَ «اذْبَحُوا فِي أَيِّ شَهْرٍ مَا كَانَ وَبَرُّوا اللهَ وَأَطْعِمُوا» قَالَ إِنَّا كُنَّا نُفَرِّعُ فَرَعًا فَمَا تَأْمُرُنَا؟ قَالَ فِي كُلِّ سَائِمَةٍ فَرَعٌ تَغْذُوهُ مَاشِيَتُكَ حَتَّى إِذَا اسْتَحْمَلَ ذَبَحْتَهُ فَتَصَدَّقْتَ بِلَحْمِهِ  

"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»
