Mishkat al-Masabih, 4156

'Amr b. Shu'aib, on his father's authority, said his grandfather told that God’s messenger was asked about the <i>‘aqiqa</i> and replied, “God does not like the breaking of ties (<i>‘uquq</i>),” 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 sheep for a boy and one for a girl. Abu Dawud and Nasa’i transmitted it.

وَعَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ: سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنِ الْعَقِيقَةِ فَقَالَ: «لَا يُحِبُّ اللَّهُ الْعُقُوقَ» كَأَنَّهُ كَرِهَ الِاسْمَ وَقَالَ: «مَنْ وُلِدَ لَهُ وَلَدٌ فَأَحَبَّ أَنْ يَنْسِكَ عَنْهُ فَلْيَنْسِكْ عَنِ الْغُلَامِ شَاتَيْنِ وَعَنِ الْجَارِيَةِ شَاةً» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ
