Abdur-Razzaq عبد الرزاق بن همام · Sacrifice (Kitab Al-Dahaya)

The Messenger of Allah (ﷺ) distributed sacrificial animals among his Companions. He gave me a kid (of less than a year). I took it to him and said: This is a kid. He said: Sacrifice it. so I sacrificed it.

Prophet (ﷺ) sa saying: There is no fara' and 'atirah.

The Prophet (ﷺ) said: A boy is in pledge for his Aqiqah, Sacrifice is made for him on the seventh day, his head is shaved and he is given name. Abu Dawud said: The word wa yusamma is sounder as narrated by Salam b. Abi Muti' from Qatadah, and narrated by Iyas b. Daghfal and Ash'ath from al-Hassan who narrated wa yusamma (and he is given a name).

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.
