ibn Abbas · Sacrifice (Kitab Al-Dahaya)

I entered upon al-Hakam b. Ayyub along with Anas. He saw some youths or boys who had set up a hen and shooting at it. Anas said: The Messenger of Allah (ﷺ) forbade to kill an animal in confinement.

explaining the verse "But the evil ones ever inspire their friend to contend with you" They used to say: Do not eat which Allah killed, but eat which you slaughtered. So Allah revealed the verse: "Eat not of (meats) on which Allah's name hath not been pronounced"...to the end of the verse.

The Jews came to the Prophet (ﷺ) and said: We eat which we kill but we do not eat which Allah kills? So Allah revealed: "Eat not of (meats) on which Allah's name hath not been pronounced." to the end of the verse.

To remove the injury is the shaving of the head.
