عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا فَرَعَ وَلَا عَتِيرَةَ قَالَ ابْنُ شِهَابٍ وَالْفَرَعُ كَانَ أَهْلُ الْجَاهِلِيَّةِ يَذْبَحُونَ أَوَّلَ نِتَاجٍ يَكُونُ لَهُمْ وَالْعَتِيرَةُ ذَبِيحَةُ رَجَبٍ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: There is no Fara’ and no ‘Atirah. Ibn Shihab said: Fara’ refers to the first offspring born, which the people of ignorance used to slaughter, and the sacrifice of Rajab is called ‘Atirah.
