Ikrama عكرمة · 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.

The verse: "So eat of (meats) on which Allah's name hath been pronounced" and the verse: "Eat not of (meats) on which Allah's name hath not been pronounced" were abrogated, meaning an exception was made therein by the verse: "The food of the people of the Book is lawful unto you and yours is lawful unto them."

AbulUshara' reported on the authority of his father: He asked: Messenger of Allah, is the slaughtering to be done only in the upper part of the breast and the throat? The Messenger of Allah (ﷺ) replied: If you pierced its thigh, it would serve you. Abu Dawud said: This is the way suitable for slaughtering an animal which has fallen into a well or runs loose.

To remove the injury is the shaving of the head.
