Sunan Ibn Majah, Book 27, Hadith 3287 (In-Book) ⓘ

It was narrated that Nubaishah said: “A man called the Messenger of Allah 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.’”

حَدَّثَنَا أَبُو بِشْرٍ، بَكْرُ بْنُ خَلَفٍ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ أَبِي الْمَلِيحِ، عَنْ نُبَيْشَةَ، قَالَ نَادَى رَجُلٌ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّا كُنَّا نَعْتِرُ عَتِيرَةً فِي الْجَاهِلِيَّةِ فِي رَجَبٍ فَمَا تَأْمُرُنَا قَالَ ‏"‏ اذْبَحُوا لِلَّهِ عَزَّ وَجَلَّ فِي أَىِّ شَهْرٍ مَا كَانَ وَبَرُّوا اللَّهَ وَأَطْعِمُوا ‏"‏ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ إِنَّا كُنَّا نُفْرِعُ فَرَعًا فِي الْجَاهِلِيَّةِ فَمَا تَأْمُرُنَا قَالَ ‏"‏ فِي كُلِّ سَائِمَةٍ فَرَعٌ تَغْذُوهُ مَاشِيَتُكَ حَتَّى إِذَا اسْتَحْمَلَ ذَبَحْتَهُ فَتَصَدَّقْتَ بِلَحْمِهِ - أُرَاهُ قَالَ - عَلَى ابْنِ السَّبِيلِ فَإِنَّ ذَلِكَ هُوَ خَيْرٌ ‏"‏ ‏.‏
