Narrated Abu Hurairah: That the Messenger of Allah (ﷺ) said: "There is no Fara' or 'Atirah." The Fara' is the first of the offspring that would be born to them, so they would slaughter it. The 'Atirah was an animal that they would slaughter during Rajab to honor the month of Rajab, since it was the first of the sacred months.

حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ فَرَعَ وَلاَ عَتِيرَةَ ‏"‏ ‏.‏ وَالْفَرَعُ أَوَّلُ النِّتَاجِ كَانَ يُنْتَجُ لَهُمْ فَيَذْبَحُونَهُ ‏.‏ قَالَ وَفِي الْبَابِ عَنْ نُبَيْشَةَ وَمِخْنَفِ بْنِ سُلَيْمٍ وَأَبِي الْعُشَرَاءِ عَنْ أَبِيهِ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏ وَالْعَتِيرَةُ ذَبِيحَةٌ كَانُوا يَذْبَحُونَهَا فِي رَجَبٍ يُعَظِّمُونَ شَهْرَ رَجَبٍ لأَنَّهُ أَوَّلُ شَهْرٍ مِنْ أَشْهُرِ الْحُرُمِ وَأَشْهُرُ الْحُرُمِ رَجَبٌ وَذُو الْقَعْدَةِ وَذُو الْحِجَّةِ وَالْمُحَرَّمُ وَأَشْهُرُ الْحَجِّ شَوَّالٌ وَذُو الْقَعْدَةِ وَعَشْرٌ مِنْ ذِي الْحِجَّةِ كَذَلِكَ رُوِيَ عَنْ بَعْضِ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم وَغَيْرِهِمْ فِي أَشْهُرِ الْحَجِّ.‏
