Ma'mar bin Rashid معمر بن راشد · Sacrifice (Kitab Al-Dahaya)

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.

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

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.
