Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) sacrificed two horned, spotted rams.

Sayyidah Aisha (may Allah be pleased with her) narrates that the Prophet (peace be upon him) used to offer a cow as sacrifice on behalf of his wives.

Sayyiduna Jabir (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: Do not slaughter any animal except a musinnah (one with permanent teeth), but if it becomes difficult to find, then slaughter a one-year-old lamb.

Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him) narrates that we sacrificed a one-year-old lamb in the company of the Messenger of Allah (peace and blessings of Allah be upon him).

Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) forbade us from sacrificing such an animal whose ear is cut from the front, or cut from the back, cut lengthwise, or cut in a circular manner, or whose nose is cut.

Ubaid bin Firoz (may Allah have mercy on him) says: I asked Sayyiduna Bara bin Azib (may Allah be pleased with both of them): Which sacrificial animal did the Prophet (peace and blessings of Allah be upon him) dislike? Or which kind of sacrifice did he forbid? He replied: My hand is smaller than the hand of the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) said: Four types of animals are not sufficient: the one-eyed animal whose defect is obvious; the lame animal whose lameness is completely evident; the sick animal whose sickness is apparent; the emaciated animal whose bones have no marrow. I said: I also dislike defects in the teeth, horns, and ears. So he (Sayyiduna Bara bin Azib, may Allah be pleased with both of them) said: Leave what you dislike, but do not declare it forbidden for anyone.

Sayyiduna Bara’ bin Azib (may Allah be pleased with both of them) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: No one should slaughter an animal (for sacrifice) before the (Eid) prayer. Sayyiduna Bara’ (may Allah be pleased with both of them) says: My uncle Abu Burdah bin Niyar stood up and said: O Messenger of Allah! On this day there is a lot of meat, I have already slaughtered my sacrifice so that my neighbors and family may eat from it. I have a one-year-old goat, which is better than two goats with more meat. Should I slaughter it (as a sacrifice)? He said: Yes! But after you, it will not suffice for anyone, and it is better for you than two sacrifices.

Qatadah (may Allah have mercy on him) says: I heard Sayyiduna Anas bin Malik (may Allah be pleased with him) narrate, so I asked him: Did you hear this yourself (from the Prophet صلی اللہ علیہ وسلم )? He replied: Yes! The Messenger of Allah صلی اللہ علیہ وسلم used to sacrifice two horned, black and white rams, and he would say“Bismillah, Allahu Akbar.”I saw that he was slaughtering them with his blessed hand and had his blessed foot placed upon them.
