When a boy was born to one of us in the pre-Islamic period, we sacrificed a sheep and smeared his head with its blood; but when Allah brought Islam, we sacrificed a sheep, shaved his head and smeared his head with saffron.
Sunan Abi Dawud Book 16, Hadith 56
← Previous Hadith 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.

Sunan Abi Dawud Book 16, Hadith 55 Next Hadith → The Prophet (ﷺ) as saying: If anyone gets a dog, except a sheeping or hunting or a farm dog, a qirat of his reward will be deducted daily.
