"O Messenger of Allah! (What about) the Fara'?" He said: "It is a duty, but if you leave it (the animal) until it becomes half-grown and you load upon it (in Jihad) in the cause of Allah or give it to a widow, that is better than if you slaughter it (when it is just born) and its flesh is difficult to separate from its skin, then you turn your vessel upside down (because you will no longer be able to get milk from the mother) and you cause your she-camel to grieve (at the loss of its young)." They said: "O Messenger of Allah, (what about) the 'Atirah?" He said: "The 'Atirah is a duty." (Hasan) Abu 'Abdur-Rahman (An-Nasa'i) said: Abu 'Ali Al-Hanafi (one of the narrators); they are four brothers: One of them is Abu Bakr, and Bishr, and Sharik, and the other. (Using translation from Nasāʾī 4225)   

عَنْ أَبِيهِ وَزِيدَ بْنِ أَسْلَمَ قَالُوا يَا رَسُولَ اللهِ الْفَرَعُ قَالَ «حَقٌّ وَأَنْ تَتْرُكَهُ حَتَّى يَكُونَ بِكْرًا فَتَحْمِلُ عَلَيْهِ فِي سَبِيلِ اللهِ أَوْ تُعْطِيَهُ أَرْمَلَةً خَيْرٌ مِنْ أَنْ تَذْبَحَهُ يَتَلَصَّقُ لَحْمُهُ بِوَبَرِهِ فَتُكْفِئَ إِنَاءَكَ وَتُوَلِّهِ نَاقَتَكَ» قَالُوا يَا رَسُولَ اللهِ وَالْعَتِيرَةُ؟ قَالَ «الْعَتِيرَةُ حَقٌّ»  

On his father's authority, said that his grandfather that the Messenger of Allah ﷺ was asked about the aqiqah. He replied: Allah does not like the breaking of ties (uquq), as though he disliked the name. And he said: If anyone has a child born to him and wishes to offer a sacrifice on its behalf, he may offer two resembling sheep for a boy and one for a girl. And he was asked about fara'. He replied: Fara' is right. If you leave it (i.e. let it grow till it becomes a healthy camel of one year or two years, then you give it to a widow or give it in the path of Allah for using it as a riding beast, it is better than slaughtering it at the age when its meat is stuck to its hair, and you turn over your milking vessel and annoy your she-camel. (Using translation from Abū Dāʾūd 2842)   

أَنَّ النَّبِيَّ ﷺ قَالَ ح قَالَ وَحَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الْأَنْبَارِيُّ ثنا عَبْدُ الْمَلِكِ بْنِ عَمْرٍو وَعَنْ دَاوُدَ عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ أُرَاهُ عَنْ جَدِّهِ قَالَ سُئِلَ النَّبِيُّ ﷺ عَنِ الْعَقِيقَةِ فَذَكَرَهُ وَقَالَ وَسُئِلَ عَنِ الْفَرَعِ قَالَ وَالْفَرَعُ حَقٌّ وَأَنْ تَتْرُكُوهُ حَتَّى يَكُونَ بَكْرًا شَعُوبًا ابْنَ مَخَاضٍ أَوِ ابْنَ لَبُونٍ فَتُعْطِيَهُ أَرْمَلَةً أَوْ تَحْمِلَ عَلَيْهِ أَوْ فِي سَبِيلِ اللهِ خَيْرٌ مِنْ أَنْ تَذْبَحَهُ فَيَلْزَقَ لَحْمُهُ بِوَبَرِهِ تَكْفَأَ إِنَاءَكَ وَتُوَلِّهَ نَاقَتَكَ
