Yazid Dhi Misr says: I came to Sayyiduna Utbah bin Abd Salma (may Allah be pleased with him) and said: O Abu al-Walid! I had gone out to buy a sacrificial animal, but I did not find any that I liked, except for one animal whose front tooth was broken. What do you say about it? He said: Why did you not bring it to me? I said: Subhan Allah, is it permissible for you and not permissible for me? He said: Yes, absolutely, because you doubt and I do not doubt. The Messenger of Allah (peace and blessings be upon him) forbade those animals: whose ear is cut so much that its hole becomes visible, whose entire ear is cut off, the one with a squinting eye, the one whose eye has become blind, the one that cannot walk behind the goats due to weakness and inability, and the one whose bones have no marrow. (Further, the meanings of these words are explained, which have been clarified in the translation.)

Ubaid bin Firoz asked Sayyiduna Bara’ (may Allah be pleased with him) about sacrificial animals: from which types of animals did the Messenger of Allah (peace and blessings be upon him) prohibit and dislike? He said: The Messenger of Allah (peace and blessings be upon him) stood among us and, gesturing with his hand in this manner—while my hand is smaller than his (peace and blessings be upon him)—he said: Four types of animals are not sufficient for sacrifice: (1) The cross-eyed one, whose cross-eyedness is obvious. (2) The sick one, whose sickness is obvious. (3) The lame one, whose lameness is obvious. (4) Such an emaciated animal that there is no marrow in its bones. I said: I also dislike defects in the horn, ear, or teeth. He said: Whatever you dislike, leave it, but do not declare it unlawful for others.

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him), he says: I bought a ram for sacrifice, but a wolf attacked it and took away its haunch. Then when I asked the Noble Prophet (peace and blessings be upon him) about this, he (peace and blessings be upon him) said: You can sacrifice it.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: A one-year-old sheep from the sheep breed is better than a mature goat from the goat breed. Dawud said: By "mature" is meant a large (good and healthy animal).

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: A light gray-colored animal is more beloved and superior than two black-colored animals.

It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him and his family) would sacrifice two fat, horned, spotted, castrated rams. One ram was on behalf of his Ummah, for those among them who affirmed the Oneness (Tawheed) of Allah and bore witness to the Messenger’s (peace and blessings be upon him and his family) message, and the other was on behalf of himself and his family.

It is narrated from Sayyiduna Abu Darda (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sacrificed two rams; both were of the age of Jadh'a and castrated.

Mawla of the Messenger, Sayyiduna Abu Rafi’ (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him and his family) sacrificed two piebald, castrated rams. One ram was on behalf of the Oneness of Allah Almighty and for those who conveyed the message on behalf of the Messenger of Allah (peace and blessings be upon him and his family), and the other ram was on behalf of the Prophet (peace and blessings be upon him and his family) and his family. Sayyiduna Abu Rafi’ (may Allah be pleased with him) says: It is as if the Messenger of Allah (peace and blessings be upon him and his family) sufficed us.

It is narrated from Sayyiduna Abdullah bin Abbas, may Allah be pleased with them both, he says: We were on a journey with the Noble Prophet, peace and blessings be upon him, when the occasion of Eid al-Adha arrived, so we slaughtered a cow on behalf of seven people and a camel on behalf of ten people.

Sayyiduna Abdullah bin Hisham (may Allah be pleased with him), who met the Noble Prophet (peace and blessings be upon him), and that was in such a way that his mother, Sayyida Zainab bint Humayd (may Allah be pleased with her), took him to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! Take his pledge (of allegiance). The Prophet (peace and blessings be upon him) said: He is just a child. Then the Prophet (peace and blessings be upon him) passed his hand over his head and prayed for him. This companion narrates that the Messenger of Allah (peace and blessings be upon him) used to sacrifice one goat on behalf of all his family.
