We were staying with the Messenger of Allah (ﷺ) at Arafat; he said: O people, every family must offer a sacrifice and an atirah. Do you know what the atirah is? It is what you call the Rajab sacrifice.

Abu Dawud said: 'Atirah has been abrogated, and this tradition is an abrogated one.

The Prophet (ﷺ) said: I have been commanded to celebrate festival ('Id) on the day of sacrifice, which Allah, Most High, has appointed for this community. A man said: If I do not find except a she-goat or a she-camel borrowed for milk or other benefits, should I sacrifice it? He said: No, but you should clip your hair , and nails, trim your moustaches, and shave your pubes. This is all your sacrifice in the eyes of Allah, Most High.

I saw Ali sacrificing two rams; so I asked him: What is this? He replied. The Messenger of Allah (ﷺ) enjoined upon me to sacrifice on his behalf, so that is what I am doing.

The Prophet (ﷺ) as saying: If anyone has sacrificial animal and intends to sacrifice it, and he sights the new moon of Dhul-Hajjah, he must not take any of his hair and nails until he sacrifices

Abu Dawud said: The name of 'Amr b. Muslim in the chain narrated by Malik and Muhammad b. 'Amr is disputed. Some say that it is 'Umar and the majority holds that it is 'Amr.

Abu Dawud said: He is 'Amr b. Muslim b. Ukaimah al-Laithi al-Jundu'i.

The Prophet (Saws) ordered a horned ram with black legs, black belly and black round the eyes, and it was brought from him to sacrifice. He said: 'Aishah, get the knife then he said: Sharpen it with a stone. So I did. He took it, then take the ram he placed it on the ground and slaughtered it. He then said: In the name of Allah. O Allah, accept it for Muhammad, Muhammad's family and Muhammad's people. Then he sacrificed it.

The Prophet (ﷺ) sacrificed seven camels standing with his own hand, and sacrificed at Medina two horned rams which were white with black markings.

The Prophet (ﷺ) sacrificed two horned rams which were white with black markings, slaughtered, and uttered: "Allah is Most Great." and mentioned Allah's name and placed his foot on their sides.

The Prophet (ﷺ) sacrificed two horned rams which were white with black markings and had been castrated. When he made them face the qiblah, he said: I have turned my face towards Him. Who created the heavens and the earth, following Abraham's religion, the true in faith, and I am not one of the polytheists. My prayer, and my service of sacrifice, my life and my death are all for Allah, the Lord of the Universe, Who has no partner. That is what I was commanded to do, and I am one of the Muslims. O Allah it comes from Thee and is given to Thee from Muhammad and his people. In the name of Allah, and Allah is Most Great. He then made sacrifice.

The Messenger of Allah (ﷺ) used to sacrifice a choice, horned ram with black round the eyes, the mouth and the feet.

The Messenger of Allah (ﷺ) as saying: Sacrifice only a full-grown animal unless it is difficult for you, in which case sacrifice a lamb.

The Messenger of Allah (ﷺ) distributed sacrificial animals among his Companions. He gave me a kid (of less than a year). I took it to him and said: This is a kid. He said: Sacrifice it. so I sacrificed it.

On the authority of his father: We were with a man from the Companions of the Prophet (ﷺ) called Mujashi' who belonged to Banu Sulaim. There was a scarcity if goats (in those days). He commanded a man to announce (among the people); so he announced that the Messenger of Allah (ﷺ) used to say: A lamb may be given as full payent for that for which has full-grown animal is payment.

Abu Dawud said: His name is Mujashi' b. Mas'ud.

The Messenger of Allah (ﷺ) delivered a sermon to us on the day of sacrifice after the prayer. He said: If anyone prays like our prayer, and sacrifices like our sacrifice, his sacrifice is all right. If anyone sacrifices before the prayer (for 'Id), that is goat meant for flesh. Abu Burdah b. Niyar stood up and said: Messenger of Allah, I swear by Allah, I sacrificed before I went for prayer. I thought it was the day of eating and drinking; so I made haste, and ate myself, and supplied flesh to my family and neighbors. The Messenger of Allah (ﷺ) said: That is a goat meant for eating flesh. He said: I have a kid (of less than a year) which is better than two goats meant for flesh. Will it be valid from me ? He said: Yes, but it will not be valid for anyone after you.

A maternal uncle of mine called AbuBurdah sacrificed before the prayer (for 'Id). The Messenger of Allah (ﷺ) said: Your goat is meant for flesh. He said: Messenger of Allah, I have a domestic kid with me. He said: Sacrifice it, but it is not valid for any man other than you.

I asked al-Bara' ibn Azib: What should be avoided in sacrificial animals? He said: The Messenger of Allah (ﷺ) stood among us, and my fingers are smaller than his fingers, and my fingertips are smaller than his fingertips. He said (pointing with his fingers): Four (types of animals) should be avoided in sacrifice: A One-eyed animal which has obviously lost the sight of one eye, a sick animal which is obviously sick, a lame animal which obviously limps and an animal with a broken leg with no marrow. I also detest an animal which has defective teeth. He said: Leave what you detest, but do not make it illegal for anyone.

Abu Dawud said: (By a lean animal mean) and animal which has no marrow.

I came to Utbah ibn AbdusSulami and said: AbulWalid, I went out seeking sacrificial animals. I did not find anything which attracted me except an animal whose teeth have fallen. So I abominated it. What do you say (about it)? He said: Why did you not bring it to me? He said: Glory be to Allah: Is if lawful for you and not lawful for me? He said: Yes, you doubt and I do not doubt. The Messenger of Allah (ﷺ) has forbidden an animal whose ear has been uprooted so much so that its hole appears (outwardly), and an animal whose horn has broken from the root, and an animal which has totally lost the sight of its eye, and an animal which is so thin and weak that it cannot go with the herd, and an animal with a broken leg.

The Messenger of Allah (ﷺ) enjoined upon us to pay great attention to the eye and both ears, and not to sacrifice a one-eyed animal, and an animal with a slit which leaves something hanging at the front or back of the ear, or with a lengthwise slit with a perforation in the ear. I asked AbuIshaq: Did he mention an animal with broken horns and uprooted ears? He said: No. I said: 'What is the Muqabalah ?' He replied: 'It has been cut from the back of its ear.' I said: 'What about the Sharqa'? He replied: 'The ear has been split.' I said: 'What about the Kharqa'? He replied: 'A hole is made (in its ears) as a distinguishing mark.'"

The Prophet (ﷺ) prohibited to sacrifice an animal with a slit ear and broken horn.

Abu Dawud said: The narrator Jurayy (b. Kulaib) is Sadusi, and belongs to Basrah. No one narrated traditions from him except Qatadah.

I asked Sa'id b. al-Musayyab: What is meant by animal with a slit ear and broken horn ? He replied: Half and more than half.
