[Machine] I witnessed the Prophet ﷺ in Arafah and he was asked about sacrificing an animal (aqeeqah). He said, "I dislike disobedience (to parents). Whoever has a child and wishes to sacrifice (an animal) on his behalf, let him do so." He was asked about sacrificing a castrated animal (al-‘ateerah). He said, "It is permissible." He was asked about dividing meat (al-fara'). He said, "It is permissible, but it is not done by slaughtering one sheep on top of another. Rather, it is done by feeding the younger one of the two (sheep), until it reaches the age of biloonee or mukhadh, meaning that you slaughter it." This is better than being extravagant with your utensil and giving it to your camel and slaughtering it, so that its meat gets mixed with its hair. This hadith was narrated by 'Abdul-Jabbar ibn al-'Ala from Sufyan, who said in the narration: "And leaving it under its mother until it becomes a biloonee or mukhadh."  

شَهِدْتُ النَّبِيَّ ﷺ بِعَرَفَةَ وَسُئِلَ عَنِ الْعَقِيقَةِ فَقَالَ لَا أُحِبُّ الْعُقُوقَ وَمَنْ وُلِدَ لَهُ وَلَدٌ وَأَحَبَّ أَنْ يَنْسُكَ عَنْهُ فَلْيَنْسُكْ وَسُئِلَ عَنِ الْعَتِيرَةِ فَقَالَ حَقٌّ وَسُئِلَ عَنِ الْفَرَعِ فَقَالَ حَقٌّ وَلَيْسَ هُوَ أَنْ تَذْبَحَهُ عُرَاةً مِنْ عُرَاةٍ وَلَكِنْ تُمَكِّنُهُ مِنْ مَالِكَ حَتَّى إِذَا كَانَ ابْنَ لَبُونٍ أَوِ ابْنَ مَخَاضٍ زُخْرُبًّا يَعْنِي ذَبَحْتَهُ وَذَلِكَ خَيْرٌ مِنْ أَنْ تَكْفَأَ إِنَاءَكَ وَتُوَلِّهَ نَاقَتَكَ وَتَذْبَحَهُ يَخْتَلِطُ لَحْمُهُ بِشَعَرِهِ وَرَوَاهُ عَبْدُ الْجَبَّارِ بْنُ الْعَلَاءِ عَنْ سُفْيَانَ فَقَالَ فِي الْحَدِيثِ وَأَنْ تَتْرُكَهُ تَحْتَ أُمِّهِ حَتَّى يَكُونَ ابْنَ لَبُونٍ أَوِ ابْنَ مَخَاضٍ
