Abu Dawud Book 9, Hadith Number 2836.

Chapter : The aqiqah.

Narated By Abdullah ibn Amr ibn al-‘As : The Apostle of Allah (PBUH) 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.
