Hameed bin Abi Hameed حميد بن أبي حميد الطويل · The Book on Sacrifices

"The Messenger of Allah (ﷺ) prohibited that an animal with a A'dab (stump) horn or ear should be slaughtered as a sacrifice." Qatadah (one of the narrators) said: "So I mentioned this to Sa'eed bin Al-Musayyab and he said: 'The A'dab is that which equals or more than that.'"

"I asked Abu Abyub how the slaughtering was done during the time of the Messenger of Allah (ﷺ). He said: 'A man would sacrifice a sheep for himself and the people in his household. They would eat from it and feed others, until the people (later) would boast about it and it became as you see now."

That the Messenger of Allah (ﷺ) said: "The best of Udhiyah (sacrifice) is a ram, and the best (burial) shroud is the Hullah."
